Question

Which one is the correct order of acidity ?
(a) CH ≡ CH > CH₃ – C ≡ CH > CH₂ = CH₂ > CH₃ – CH₃
(b) CH ≡ CH > CH₂ = CH₂ > CH₃ – C ≡ CH > CH₃ – CH₃
(c) CH₃ – CH₃ > CH₂ = CH₂ > CH₃ – C ≡ CH> CH ≡ CH
(d) CH₂ = CH₂ > CH₃ – CH = CH₂ > CH₃ – C ≡ CH > CH ≡ CH​

Which one is the correct order of acidity ?

In hydrocarbons acidity increases as the s character increases.

So the acidity order of hydrocarbons is Alkane < Alkene < Alkyne and the acidity of substituted alkyne are less than unsubstituted alkyne due to I − effect.

Hence correct order is ==> CH₂ = CH₂ > CH₃ – CH = CH₂ > CH₃ – C ≡ CH > CH ≡ CH
