Consider the reaction of 3-cyclopenten-1-one with neutral propan-2-amine (also called isopropylamine).

Part 1: Draw the expected major product of this reaction. Include all lone pairs and H atoms connected to heteroatoms.

Part 2: Draw the first step and resulting intermediate that lead to the major product. Include all lone pairs and H atoms connected to heteroatoms.

Part 3: Which factors contribute to the formation of the major product over the minor product?
Choose one or more:
A. A localized negative charge on O, which is more electronegative than C, is lower energy than a negative charge delocalized over O and C atoms.
B. The amine adds reversibly to the unsaturated ketone.
C. 1,2-addition gives an intermediate with a single negative charge, while 1,4-addition gives a zwitterion.
D. The amine nucleophile is uncharged.
E. An unstable carbanion forms from conjugate addition.
