Question

How many total substituents are present in the following compound?

(A) $ 3 $
(B) $ 4 $
(C) $ 5 $
(D) $ 6 $

Answer 1

Hint :We know that the branched piece of a given molecule is called a substituent. The substituents that are made from alkanes are called alkyl groups. These alkyl groups are named similarly to unbranched alkane chains. To solve this question, first identify the longest carbon chain and then count the number of branches of alkyl and halo groups.

Complete Step By Step Answer:
Substituents are atoms or groups of atoms that are directly attached to the longest carbon chain of the given compound. Alkyl and halo groups are considered as substituents. Find the longest carbon chain in the given compound. Here, the longest carbon chain has seven carbon atoms in it. Then count the number of branches that are directly attached to the longest carbon chain. There are two methyl groups, one ethyl group, one chloro and one iso propyl bromide group attached to the longest carbon chain of the given compound. In the given compound, there are five substituents in the given compound.
Therefore, option C is the correct answer.

Note :
In organic chemistry, substituent is a single atom or a group of atoms that take the position of another atom in a molecule. That means they replace this atom. This reaction is called a substitution reaction and the atom or group of atoms that are replaced is called the leaving group. A substituent is also called a side chain, group, branch or pendant group.
