In the monochlorination of hydrocarbons, a hydrogen atom is replaced by a chlorine atom. How many different monochloro derivatives of 2 -methylbutane are possible?

Short Answer

Expert verified
The number of possible monochloro derivatives of 2-methylbutane is 3.

Step by step solution

01

Draw the structure of 2-methylbutane

Identify the structure of 2-methylbutane. It's a five-carbon chain with a methyl group (an extra carbon) attached to the second carbon. Write the structure out and mark each hydrogen atom.
02

Identify positions for chlorination

Identify unique positions where hydrogen atoms can be replaced by a chlorine atom. There are three unique positions: one on the end carbon atom (primary carbon), one on the second carbon atom (tertiary carbon), and one on the middle carbon atom (secondary carbon).
03

Count the derivatives

Count the number of different monochlorinated products that can be formed by replacing a hydrogen atom at each position. Each unique position leads to a different structural isomer. Therefore, replacing a hydrogen atom at each of these positions produces a total of 3 unique monochloro derivatives of 2-methylbutane.
