$CH_3 - C \equiv CH$

Vedclass · Answer

(C) The acidity of hydrocarbons depends on the $s$-character of the carbon atom involved in the $C-H$ bond. Terminal alkynes like $CH_3 - C \equiv CH$ are weakly acidic because the $sp$-hybridized carbon atom is more electronegative,allowing the proton to be removed by a strong base. $CH_2 = CH_2$ $(sp^2)$ and $C_6H_6$ $(sp^2)$ are much less acidic. $CH_3 - C \equiv C - CH_3$ has no acidic hydrogen atom attached to the $sp$-hybridized carbon,so it is not acidic. Therefore,$CH_3 - C \equiv CH$ is the correct answer.
