Solution

The correct option is C Iso-butane
Due to stability of $2^{o} -$ radical, it is easy to synthesize Iso-butane,
The Wurtz reaction is a coupling reaction in organic chemistry, whereby two alkyl halides are reacted with sodium metal in dry ether solution to form a higher alkane: $2 R - X + 2 N a \to R - R + 2 N a^{+} X^{-}$
