Problem- Compound A reacts with methylmagnesium bromide to give, after hydrolysis, compound B. Reaction of B with sodium dichromate gives C, C5H10O, which gives a crystalline product with 2, 4-dinitrophenylhydrazine and a positive iodoform test. Explain your reasoning give the structures of A, B, C and equations for all reactions mentioned.
Explain the each and every step in detail for help
