Organic Compound Identification: Identification of Compound A (C₄H₉Cl)

An organic compound A (C₄H₉Cl) on reaction with Na/diethyl ether gives a hydrocarbon which on monochlorination gives only one chloro derivative.

What is A?

Compound A is tert-butyl chloride (2-chloro-2-methylpropane).

- The Wurtz reaction between two identical tert-butyl chloride molecules produces 2,2-dimethylpropane.
- Monochlorination of 2,2-dimethylpropane yields only one possible chloro derivative, as all the hydrogens are chemically equivalent.
