Question

[X] as the major product among the elimination products is:

(B)

(C)

(D)

Answer 1

Hint: Here in the question we have to find the product of the given reaction in which we have to do the reaction between the given ring expansion as in the presence of Methanol and applied some heat to that reaction we have to find the solution of the reaction.

Complete Step by Step Solution:
As by seeing the above equation, we know that when any reaction held in the presence of Methanol it eliminates some bonds of the reactants and have convert them into the double bonds of the rings.
So, by making the whole reaction we get that,


By seen full steps of the reaction we get that firstly bromide is eliminated from the reaction as in the presence of methanol and a plus charge is applied on the centred carbon atom. After which it is converted to the Ring base structure made a double bond at that side.
As a Result, we get the correct answer as the structure provided on the (C) option.
Hence, the correct option is (C).

Note: This question is taken from Haloalkanes and Haloarenes. So, let’s we know that what are haloalkanes and haloarenes. Haloalkanes are those which contains alkanes with having halogens as in their substituents and in Haloarenes are those when any hydrogen atom is bonded to the benzene ring and got replaced by the halogen atoms and the compound which form from the whole reaction the compound is called as by the name of Haloarenes.
