Question

Which one of the following carbonyl compounds cannot be prepared by addition of water on an alkyne in the presence of HgSO 4 and H 2 SO 4 ? (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

Reaction of HgSO 4 / dil. H 2 SO 4 with alkyne gives addition of water as per markonikoff's rule.

Hence CH 3- CH 2- CHO cannot be form.

Q. Which one of the following carbonyl compounds cannot be prepared by addition of water on an alkyne in the presence of $H g S O_{4}$ and $H_{2} S O_{4}$ ?

Reaction of $H g S O_{4} / d i l . H_{2} S O_{4}$ with alkyne gives addition of water as per markonikoff's rule.

Hence $C H_{3} - C H_{2} - C H O$ cannot be form.

Q. Which one of the following carbonyl compounds cannot be prepared by addition of water on an alkyne in the presence of HgSO4​ and H2​SO4​ ?

Reaction of HgSO4​/dil.H2​SO4​ with alkyne gives addition of water as per markonikoff's rule. Hence CH3​−CH2​−CHO cannot be form.
