For I, II and III, negative charge after removal of H+ comes on sp3 hybridised carbon
For IV, negative charge after removal of H+ comes on sp2 hybridised carbon
For V, negative charge after removal of H+ comes on sp hybridised carbon
sp hybridised carbon are most electronegative because of greater
% s character. Due to this, negative charge is more stable on
carbon in V.
So, V is most acidic
Answer: V
