Alcohol starting material is: 2) ethanol
Reagent for step 1: g) CrO3
Reagent for step 2: e) SOCl2
Reagent for step 3: l) C6H5MgBr (phenylmagenesium bromide)
Explanation: CrO3 is a strong oxidising agent which oxidises alcohol, ethanol to carboxylic acid. Reaction of carboxylic acid with SOCl2 produces acid chloride as product. Reaction of grignard reagent, C6H5MgBr (phenylmagenesium bromide) with acid chloride produces the required ketone as product.
