Q. Hydrocarbon (A) reacts with bromine by substitution to form an alkyl bromide which by Wurtz reaction is converted to gaseous hydrocarbon containing less than four carbon atoms. (A) is
A) $CH_3-CH_3$
B) $CH_2=CH_2$
C) $CH\equiv CH$
D) $CH_4$
Explanation
[Solution] $CH_4 \rightarrow CH_3Br \xrightarrow{Wurtz} C_2H_6$ (2 C). Ethane would give butane (4 C). Answer (4).
