Show Answer
Answer:
Correct Answer: D
Solution:
$ CH\equiv CH\xrightarrow{NaNH_2}CH\equiv {C^{-}}N{a^{+}}\underset{-NaI}{\mathop{\xrightarrow{CH_3I}}}CH\equiv C-CH_3 $
$ \underset{Pent-2-yne}{\mathop{C_2H_5-C\equiv C-CH_3}}\underset{-NaI}{\mathop{\xleftarrow{C_2H_5I}}}N{a^{+}}{C^{-}}\equiv C-CH_3 $
