Question

Which following carbon atom(s) will be bonded to an oxygen atom in the major organic product(s) of Reaction C? The protic solvent mentioned is not water. Also, it is an SN1 reaction on a secondary position. Please carry out the reaction via SN1 with a carbocation rearrangement to the neighboring tertiary position. Subsequent attack by the internal OH completes this reaction. Justify your response.

Explanation / Answer

the ans is 2 and 6

as there will be an internal attack by the OH group on the br and after that the ring will open to form a C+ at position 4 which will rearrange to position 2 as there are more no. of alpha H so the OH will be atttached on 2 and 6 carbons
