Homework Answers
PCC is a mild oxidising agent and oxidize the Alcohol to aldehyde. Then Grignard reagent is more reactive towards aldehyde than Ketone. Hence grigGrig reagent gives secondary alcohol with aldehyde first then protection of alcohol by ether since OH is Grignard reagent sensitive. Then reaction of ketone with Grignard reagent gives tertiary alcohol them followed by deprotection of Ether by Lewis acid.
