Answer 1

1a. Which method will not make a ketone?

solution :- 1-propanol + PCC will not make ketone because primary alcohol forms aldehyde on oxidation.

2-methylpropene + O3 = will make ketone

propyne + H2SO4/HgSO4 = will make ketone

1b. The carbonyl carbon in acetone is a ___ than ____. It reacts with a _____ to form a ____ intermediate.

solution :-

Part 1 = poorer electrophile

Part 2 = OH- to form tetrahedral

1c. 1 equivalent of ROH reacts with acetone with a ____ catalyst to form a ____.

solution :- when acetone reacts with ROH then it forms acid /hemiacetal

1d. Acetone reacts with methyl amine to form a:

Solution :-

When the acetone react with methyl amine then it removes the water molecule and forms C=N bond which is called as imine
