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

Options

A. `CH -= CH`
B. `CH_2 = CH_2`
C. `CH_3 - CH_3`
D. `CH_4`

Answer

D

Explanation

`CH_(4) overset(Br_2)underset(hv//Delta)rarr CH_(3)Br overset(Na)underset("Dry ether") rarrCH_(3) - CH_(3)` `{:(CH_(4) overset(Br_2)underset(hv//Delta)rarr CH_(3)Br overset(Na)underset("Dry ether") rarrCH_(3) - CH_(3)),("A" " Free radical" " Wurtz" " Ethane"),("Methane" " mechanism" " reaction" " (Hydrocarbon)"):}`
