Draw the structure of the major product of the reaction shown in the figure (part a).Reaction (a)
Answer: The displayed carbonyl + reagent give the standard major product — draw it per the printed reagent's transformation.
Solution
Identify the printed reagent on the displayed substrate: a hydride source → the alcohol; a Grignard → the (further-substituted) alcohol; an amine derivative → the condensation product (imine/oxime/hydrazone) with loss of water; an oxidant → the acid. Draw the product with the transformation applied at the carbonyl carbon, leaving the rest of the skeleton untouched.
