Question

Acidity of terminal alkynes and alcohols. Provide an order of acidity of compounds A-D (less acidic to more acidic). Draw the corresponding conjugate bases A' and B' generated from A and B by treating with sodium amide (NaNH_2). Using the structures of A' and B', explain why there is a significant pK_a difference between A and B. When C and D are treated with sodium amide (NaNH_2) only one of them will undergo an acid-base reaction. Which compounds will react with the base used? Briefly explain why there is a significant pK_a difference between C and D on the basis of hybridized orbitals.

Explanation / Answer

Phenolic bond is most among given comounds and the vinylic bond least so the order would

B> A> D>C
