Question

The fragment benzyl cation(C6H5+CH2) can rearrange to
(a) Propyl cation
(b)Tropylium cation
(c) Pentadyl cation
(d) Cycloheptane​

Answer 1

Answer:

B. Tropylium cation is the answer

Explanation:

In organic chemistry, the tropylium ion or cycloheptatrienyl cation is an aromatic species with a formula of [C7H7]+.[4] Its name derives from the molecule tropine from which cycloheptatriene (tropylidene) was first synthesized in 1881. Salts of the tropylium cation can be stable, even with nucleophiles of moderate strength e.g., tropylium tetrafluoroborate and tropylium bromide (see below). Its bromide and chloride salts[5] can be made from cycloheptatriene and bromine or phosphorus pentachloride, respectively.[6]
