Question

What alkyl group is $- C{H_3}$?

Answer 1

We need to know that in organic chemistry, there are so many functional groups and it is a particular group of bonds or atoms which is present in the compound. And these functional groups will show characteristic chemical reactions in a compound. All the same functional groups will undergo similar chemical reactions. And these functional groups are denoted as ‘R’ and this will be found along the carbon backbone of the molecules.

Complete answer:
As we know, the alkyl group is a functional group which contains only carbon and hydrogen atoms. The general formula of an alkyl is ${C_n}{H_{2n + 1}}$. The methyl group, $- C{H_3}$ is an example of alky; group. And the methyl is derived from the methane. The alkyl group is formed by the removal of one hydrogen group which is present in that alkane chain. Then the stem changes from, -ane to –yl. The –yl represents the alkyl group. In the case of methane, one hydrogen group is removed from it, and there is a formation of methyl alkyl group.
If the alkyl group is formed by the removal of hydrogen from ethane, then the alkyl is ethyl. There are so many isomeric alkyl groups that are generally possible.

Note:
We need to know that the functional groups are divided into many types like alkyl groups, aryl groups, aliphatic and aromatic groups. The alkyl groups are formed by the removal of one hydrogen atom from an alkane chain. Then it will be converted to –ane to –yl. And the aryl group is formed by the removal of hydrogen from the aromatic ring. The aromatic group is derived from benzene.
