Concept introduction:
An alkyne can be converted into aldehyde and ketone by hydration reaction. In hydration reaction, mercuric ion with a dilute acid is used to carry out the reaction. Mercuric ion is used as a catalyst. After the protonation of the alkynyl carbon, the water attacks as the nucleophile and an enol is formed. Enol is unstable and converts into a stable aldehyde or ketone.
(c)
Interpretation:
The explanation of the statement, “The hydration of alkyne is not a reasonable preparative method for cyclohexanone ” is to be stated.

- A. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry.
