Question

How many monochlorination products can be formed (constitutional isomers only) from the reaction of (CH3)2CHCH2CH3 with Cl2 and hν?

Answer 1

Answer:

4 monochlorination products can be formed.

Explanation:

Constitutional isomers : These are those compounds with same molecular formula but different atomic arrangement.For example: butane and 2-methly-propane.

On monochlorination of 2 methyl-butane  we will have four possibilities of product which will be constitutional isomers of each other:

• 1-chloro-3-methyl butane : $(CH_3)_2CH-CH_2-CH_2-Cl$

• 2-chloro-3-methyl butane : $(CH_3)_2CH-CHCl-CH_3$

• 2-chloro-2-methyl butane $(CH_3)_2CCl-CH_2-CH_3$
• 1-chloro-2-methyl butane $(CH_2Cl)_2CH-CH_2-CH_3$
