Question

How many chiral compounds are possible on monochlorination of $2-$ methylbutane?

Answer 1

The products formation during monochlorination:

Step 1: When carbon is attached with four different substituents, then it is chiral carbon.

Step 2: When $2-$methyl butane is chlorinated four products are formed.

Step3: Only two Chiral compounds are formed in this reaction.

Here, $\mathrm{I}$and $\mathrm{III}$ compounds are Chiral compounds(marked as asterisk).

So, there are two Chiral Compounds are Possible on Monochlorination of $2-$ methyl butane
