Chemistry Question on Hydrocarbons
Which one of the following gives only one monochloro derivative?
A
neo-Pentane
B
n-Hexane
C
2-Methylpentane
D
3-Methylpentane
Answer
neo-Pentane
Explanation
Solution
neo-Pentane or 2, 2-dimethylpropane has only primary hydrogen hence it can give only monochloro derivative. All other compounds have 1∘, 2∘ and 3∘ hydrogens hence they give mono, di or trisubstituted products.
