Propose mechanisms to account for the observed products in the following reactions. In some cases more products are formed, but you only need to account for the ones shown here.
In this reaction N-bromosuccinimide (NBS) react with Br2 and generate bromine radical in presence of UV light. THe reaction has been carried out as follows:-
(b)Here the allylic carbocation has two resonance forms in which both the resonance structure has positive sign on the C atom.
The ethanol nucleophile can attack either of these carbons and forms SN1 products or loss of an adjacent H will give E1 product.
It is a 1st order solvolysis reaction and the 1st step involves ionization followed by rearrangement reaction.
