- A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.

Water is a Polar Molecule When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule. Water molecules attract one another based on the attraction between the positive end of one water molecule and the negative end of another.

CHEMISTRY II: WATER AND ORGANIC MOLECULES The difference between a polar (water) and nonpolar (ethane) molecule is due to the unequal sharing of electrons within the polar molecule. Nonpolar molecules have electrons equally shared within their covalent bonds.

Polar Molecule Definition and Examples Polar Molecule Definition: A polar molecule is a molecule containing polar bonds where the sum of all the bond's dipole moments is not zero. Examples: Water is a polar molecule. Carbon dioxide is made up of polar bonds, but the dipole moments cancel each other out and therefore is not a polar molecule. Up Next. Up Next.

Properties of Water Explain how the water molecule is polar. The oxygen atom is on one end of the molecule and the hydrogen atoms are on the other. As a result, the oxygen end of the molecule has a slight negative charge and the hydrogen end of the molecule has a slight positive charge.

Why is water excellent solvent?? When an ionic or polar compound enters water, it is surrounded by water molecules. The relatively small size of water molecules typically allows many water molecules to surround one molecule of solute.

What is a polar molecule? H2O, for example, is a polar molecule because 1) it has lone pairs 2) the oxygen is pulling the electrons from the hydrogen into its vicinity making it have a slightly negative charge while the two hydrogens have a slightly positive charge.Source(s):2O, for example, is a polar molecule because 1) it has lone pairs 2) the oxygen is pulling the electrons from the hydrogen into its vicinity making it have a slightly negative charge while the two hydrogens have a slightly positive charge.

13.3 Factors Affecting Solubility Water is not only polar but also able to form hydrogen bonds. Thus, polar molecules, and especially those that can form hydrogen bonds with water molecules, tend to be soluble in water. For example, acetone, a polar molecule whose structural formula is shown below, mixes in all proportions with water.

- The water is a polar molecule because it is not equally charged. [ Its half side has a positive charge and the other half has a negative charge because the electrons spend more of their time with the oxygen and not with hydrogen and due to this they get more negative charge and due to this the water is a polar molecule. Its half side has a positive charge and the other half has a negative charge because the electrons spend more of their time with the oxygen and not with hydrogen and due to this they get more negative charge and due to this the water is a polar molecule.

Overview Abnormal genes cause polycystic kidney disease, and the genetic defects mean the disease runs in families. Rarely, a genetic mutation can be the cause of polycystic kidney disease. There are two types of polycystic kidney disease, caused by different genetic flaws:Autosomal dominant polycystic kidney disease (ADPKD).Signs and symptoms of ADPKD often develop between the ages of 30 and 40. In the past, this type was called adult polycystic kidney disease, but children can develop the disorder.arely, a genetic mutation can be the cause of polycystic kidney disease.

Why is a water molecule polar? exists and is an alternate of. Merge this question into. Split and merge into it. Answer by Betaclamp. Confidence votes 20.9K. Since oxygen is more electronegative than hydrogen, you get something called a dipole moment, making the oxygen slightly negative because of the unequal sharing of electrons.

- Polar covalent bonds hold the actual hydrogen and oxygen atoms within the molecule of water but if you meant what holds water together as a liquid then that is called hydrogen … bonding between molecules, a type of dipole interaction.

Dipoles & Dipole Moments: Molecule Polarity Molecules that have an uneven distribution of charge and a dipole moment are called polar molecules. Another clue that a molecule is polar is the presence of lone pairs. Water has two sets of lone pairs on oxygen, making that area particularly negative.

Universal Solvent Definition Why Water Is Called the Universal Solvent. Water dissolves more chemicals than any other solvent because its polar nature gives each molecule a hydophobic (water-fearing) and hydrophilic (water-loving) side.

Water is considered a polar molecule because? Answers. Best Answer: c. it has an unequal distribution of electrons. To determine polarity, one can also look at symmetry. Water seems to be symmetrical when you draw out the structure, but because the oxygen atom has two pairs of unpaired electrons, the structure is considered polar and asymmetrical.ater seems to be symmetrical when you draw out the structure, but because the oxygen atom has two pairs of unpaired electrons, the structure is considered polar and asymmetrical.

- A water molecule is charge neutral because there is the same number of positive charges as there are negative charges. In this diagram, called a Lewis structure, the dots represent electrons while the lines or dashes represent a covalent bond of two electrons.

- The Polarity of Water. There is a simple molecular structure to water. It is comprised of one oxygen atom and two hydrogen atoms. The hydrogen atoms are bonded to the oxygen by sharing a pair of electrons. Because oxygen also holds two unshared pairs of electrons there are a total of 4 pairs of electrons that surround the oxygen atom. Because oxygen has a higher electonegativity than hydrogen, the side of the molecule with oxygen atom has a partial negative charge.

What is the term for a molecule having both a hydrophilic and hydrophobic region called? Answer   Hydrophilic, or 'water loving' refers to molecules that are easily miscible in water. lipids:     phospholipids are an example because their head is hydrophilic and their tail is hydrophobic. idontk nowtheansewrtothis question. A polar molecule is hydrophilic, which means that it will easily  dissolve in water.

Chemical polarity Water (H 2 O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other. The dipoles do not cancel out resulting in a net dipole. Due to the polar nature of the water molecule itself, polar molecules are generally able to dissolve in water. Non-polar bonds occur when the difference in electronegativity between the two atoms is less than 0.4. 2  Polar bonds occur when the difference in electronegativity between the two atoms is between 0.4 and 1.7. 3  Ionic bonds occur when the difference in electronegativity between the two atoms is greater than 1.7.

Water is a Polar Molecule 1 In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms.  The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
