Question

Which of the following compounds can be best prepared by Wurtz - reaction?

• A. Iso-butane
• B. n-butane
• C. n-pentane
• D. Iso-pentane

Answer 1

Answer: (A)

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: $2R–X+2Na\to R–R+2N{a}^{+}{X}^{-}$
