Concept explainers
(a)
Interpretation:
The mechanism for formation of limonene from the given carbocation is to be stated.
Concept introduction:
Isoprene unit contains five carbon atoms. The carbon atoms of isoprene unit are connected by sigma bond or pi bond. Terpenes and terpenoids contain unequal number of isoprene units. Limonene contains a cyclic monoterpene unit. The oil extracted from citrus peels majorly contains limonene.
(b)
Interpretation:
The curved arrow mechanism for the synthesis of carbocation intermediate from a geranyl pyrophosphate is to be stated.
