Introduction to IUPAC Naming for Carbon Compounds Chemistry Tutorial 1 The principal nomenclature used in organic chemistry, and which forms the basis of most IUPAC 3 preferred names, is substitutive nomenclature. 2  Substitutive nomenclature is based on the concept of different atoms, or groups of atoms, substituting for the atoms on a parent hydrocarbon molecule.he prefix for the name of an aliphatic parent hydrocarbon is determined by the number of carbon atoms in the chain or ring. The prefix for the first four hydrocarbons in the series is based on a traditional name and the prefix has been retained.

Nomenclature of Alkanes Introduction to Nomenclature [edit]. Before we can understand reactions in organic chemistry, we must begin with a basic knowledge of naming the compounds. The IUPAC nomenclature is a system on which most organic chemists have agreed to provide guidelines to allow them to learn from each others' works.

- Generally spoken, an amino acid is a carboxylic acid containing an amino substituent. In most cases, the term “amino acid” refers to an α-amino acid. Amino and carboxyl moiety are linked to the same carbon atom, the α-carbon. Glycine, α-aminoacetic acid, is the simplest amino acid, the parent compound of this class of substances. β-alanine is the parent compound of the β-amino acids.

What is it? Uracil is one of the four nucleobases in the nucleic acid of RNA. It is represented as the letter U when bonding with other bases in RNA. In RNA Uracil plays an important role, and binds to another base in RNA Adenine or A.Even though Uracil is found in RNA, it is replaced by another nucleobases called Thymine or T in DNA. As a pyrimidine nucleobase, Uracil is considered to be a heterocyclic aromatic organic compound.A heterocyclic compound is a cyclic compound that contains atoms of at least two different elements as a member of its ring or rings.The opposite of a heterocyclic compound is a homocyclic compound, in which the ring or rings is made of a single element.s a pyrimidine nucleobase, Uracil is considered to be a heterocyclic aromatic organic compound. A heterocyclic compound is a cyclic compound that contains atoms of at least two different elements as a member of its ring or rings.

What is the IUPAC name of the compound shown? CH3CH2COOCH3? Best Answer: The correct IUPAC name for this compound is methyl propanoate. This is an ester The reaction of propanoic acid CH3CH2COOH and methanol CH3OH can form this ester.From the IUPAC rules, the ester will take its first name from the prefix of the alcohol, in this case methyl, and the second name from the acid,propanoic acid, which gives the name propanoate.Thus CH3CH2COOCH3 is named methyl propanoate by the rules laid down for IUPAC nomenclature for esters.est Answer: The correct IUPAC name for this compound is methyl propanoate. This is an ester The reaction of propanoic acid CH3CH2COOH and methanol CH3OH can form this ester.

Organic Chemistry: Structure of Alkanes The IUPAC system considers molecules in terms of a parent hydrocarbon chain with substituents attached to it. The parent is the longest continuous carbon chain in the compound, and the base name of the compound is the alkane that corresponds to the parent chain. Then, consecutively number the carbons of the parent chain in such a way that the substituents are attached to carbons with lower numbers.
