Two alkyl halides A and B with molecular formula C_(7)H_(15)Cl have different boiling points. These are optically active in nature. On reacting with Mg dissolved in anhydrous ether and then with water, each compound gives 2,4-dimethylpentane. Suggest structures for these compounds.

Answer»

Solution :
the STRUCTURE of the hydrocarbons is:
The possible structures of the TWO isomeric haloalkanes [A] and [B] are:

These on reacting with Mg metal dissolved in anhydrous ether, form grignard reagetns which on reaction with WATER give hydrocarbon 2,4-dimethylpentane.
