Question

C12T04Q8272 Give the major product(s) of the following reaction. CrO3 он H,SO4 H. of HO, OMe HO. There is no reaction under these conditions or the correct product is not listed here.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
