Draw the correct structure of the indicated product for each reaction. The starting material is a 3 carbon chain where carbon 1 has a chloro substituent and carbon 2 has two methyl substituents. This reacts with K C N to form product 1. Product 1 reacts with hydroxide and water, followed by H 3 O plus to give product 2.
