Concept explainers
(a)
Interpretation:
To predict the compound formed by the reaction of phosgene with given compound.
Concept introduction:
Carbonyl carbon of phosgene is highly polar in nature because of the presence of electronegative groups attached to it. So phosgene will undergo nucleophilic addition-eliminationreaction. Tetrahedral intermediate is formed when nucleophile is added to the carbonyl carbon of phosgene. The tetrahedral intermediate is unstable therefore chloride ion gets eliminated. The acyl chloride reacts with neutral nucleophile by the following mechanism:
