The reagent for [1] is A
The reagent for [2] is D
option 4: (1) A (2) D is correct
Explanation: NaBH4 is a reducing agent which reduces ketone to alcohol. NaH is a strong base which abstracts -OH proton and produces oxygen anion which on further reaction with alkyl halide produces alkylated product.

Question 40 (3 points) Provide the reagents needed to achieve the following synthesis. If a sequence of reactions is used, be sure to number the reactions as 1). 2)..... 73CO Type your answer in the text box below. Don't worry about typing the numbers in a chemical formula as subscript. Just use non-subscript numbers. For example, H20 would mean H,O. In some cases, it may be easier to just type the name of the chemical Instead of its chemical formula....
