Explanation Reason for correct option: The stable benzylic carbocation intermediate is not formed in the reaction. Synthesis III- In the last step of above reaction, the carbon monoxide does not facilitate the formation of carbocation. The carbon monoxide attaches to the exocyclic chain present in the molecule. Hence, the benzylic group is not involved in the reaction. Hence, the correct option is (1). Reason for incorrect option: Option (2) tells that it involves organometallic intermediates...

Reactive Intermediates

In chemistry, reactive intermediates are termed as short-lived, highly reactive atoms with high energy. They rapidly transform into stable particles during a chemical reaction. In specific cases, by means of matrix isolation and at low-temperature reacti…

Hydride Shift

A hydride shift is a rearrangement of a hydrogen atom in a carbocation that occurs to make the molecule more stable. In organic chemistry, rearrangement of the carbocation is very easily seen. This rearrangement can be because of the movement of a carboc…

Vinylic Carbocation

A carbocation where the positive charge is on the alkene carbon is known as the vinyl carbocation or vinyl cation. The empirical formula for vinyl cation is C2H3+. In the vinyl carbocation, the positive charge is on the carbon atom with the double bond t…

Cycloheptatrienyl Cation

It is an aromatic carbocation having a general formula, [C7 H7]+. It is also known as the aromatic tropylium ion. Its name is derived from the molecule tropine, which is a seven membered carbon atom ring. Cycloheptatriene or tropylidene was first synthes…

Stability of Vinyl Carbocation

Carbocations are positively charged carbon atoms. It is also known as a carbonium ion.
