Alkane Reactions The alkanes and cycloalkanes, with the exception of cyclopropane, are probably the least chemically reactive class of organic compounds. Despite their relative inertness, alkanes undergo several important reactions that are discussed in the following section.nlike the complex transformations of combustion, the halogenation of an alkane appears to be a simple substitution reaction in which a C-H bond is broken and a new C-X bond is formed. The chlorination of methane, shown below, provides a simple example of this reaction. CH 4 + Cl 2 + energy —— CH 3 Cl + HCl.

Introduction to the Alkanes Chain compounds in which all carbon-to-carbon bonds are only simple single bonds are called ALKANES. These compounds are also called saturated hydrocarbons, because each carbon-to-carbon bond is a single bond, and the valence of the carbon atom is, therefore, saturated.

Cationic Rearrangements Many aldehydes and ketones undergo substitution reactions at an alpha carbon, as shown in the following diagram (alpha-carbon atoms are colored blue). These reactions are acid or base catalyzed, but in the case of halogenation the reaction generates an acid as one of the products, and is therefore autocatalytic.

- Alkanes. In the absence of a spark or a high-intensity light source, alkanes are generally inert to chemical reactions. However, anyone who has used a match to light a gas burner, or dropped a match onto charcoal coated with lighter fluid, should recognize that alkanes burst into flame in the presence of a spark.hen Br 2 in CCl 4 is mixed with a sample of an alkane, no change is initially observed. When it is mixed with an alkene or alkyne, the color of Br 2 rapidly disappears. The reaction between 2-butene and bromine to form 2,3-dibromobutane is just one example of the addition reactions of alkenes and alkynes.

- Addition Reactions of Alkenes. The most common chemical transformation of a carbon-carbon double bond is the addition reaction. A large number of reagents, both inorganic and organic, have been found to add to this functional group, and in this section we shall review many of these reactions.

- Alkanes. Crude oil forms naturally over millions of years from the remains of living things. Most of the compounds in crude oil are hydrocarbons. These are compounds that contain hydrogen and carbon atoms only, joined together by chemical bonds called covalent bonds.he alkanes are a family of hydrocarbons that share the same general formula. This is: CnH2n+2. The general formula means that the number of hydrogen atoms in an alkane is double the number of carbon atoms, plus two.

- THE HYDROGENATION OF ALKENES. This page looks at the reaction of the carbon-carbon double bond in alkenes with hydrogen in the presence of a metal catalyst. This is called hydrogenation. It includes the manufacture of margarine from animal or vegetable fats and oils. Hydrogenation in the lab. The hydrogenation of ethene.

What is Hydrocarbon? - Definition, Formula & Compounds Alkanes are linear, or branching, compounds that are made of varying numbers of carbon atoms that are all saturated with hydrogen atoms. The formula for an alkane is CnH(2n+2). This means that the number of hydrogen atoms equals twice the number of carbon atoms, plus two. Methane is the simplest hydrocarbon possible.

Hydrogenation Typical hydrogenation reactions include the reaction of hydrogen and nitrogen to form ammonia and the reaction of hydrogen and carbon monoxide to form methanol or hydrocarbons, depending on the choice of catalyst.

This page Double-bonded carbons are sp 2 -hybridized, and have trigonal planar shapes, with the bonded atoms at angles of 120 to each other. Free rotation is not possible around carbon-carbon double bonds in alkenes, making the carbon chains less flexible and floppy than those of alkanes with the same number of carbons.heir general formula is C n H 2n for molecules with one double bond (and no rings). Alkenes are also known as olefins, after the original name for ethene, olefiant gas. Alkenes take part in a wide variety of chemical reactions, and are found as parts of many highly colored systems (see below for examples).

- Wikipedia the reaction. You put an alkane and o2 to get CO2, H2O and energy as the products. Also, one way to think about it is that exothermic reactions are ones in which the bonds made by the products are stronger than those of the reactants.Since you have h-bonding with H2O, those bonds are inevitably gonna be stronger.ou put an alkane and o2 to get CO2, H2O and energy as the products.

Alkanes Alkyl Groups. If a hydrogen is removed from an alkane, it can be used as a substituent functional group called an alkyl group. Alkyl groups are named by dropping the-ane suffix of the alkanes and adding the suffix-yl. Methane becomes a methyl group, ethane an ethyl group, etc.lkyl Groups.

Saturated Hydrocarbons Alkanes and cycloalkanes are termed saturated, because they incorporate the maximum number of hydrogens possible without breaking any carbon-carbon bonds. They are also members of a larger class of compounds referred to as aliphatic.he alkanes and cycloalkanes, with the exception of cyclopropane, are probably the least chemically reactive class of organic compounds. Despite their relative inertness, alkanes undergo several important reactions that are discussed in the following section.
