Answer #1

Answer:

As we have five carbon alkyl halide which needs to be converted to six carbon alkyl amine.

So we need to react with NaCN to produce the cynide group.

Followed by reducing the cynide with LiAlH4 to have six carbon amine

CH3-(CH2)4-Br + NaCN --->CH3-(CH2)4-CN ------------> react with LIAlH4 + H2O -------> CH3-(CH2)5-NH2

The reaction shows as below:

CH3-(CH2)4-Br + NaCN --->CH3-(CH2)4-CN (Nucleophilic substitution)

Now further reaction shows in the belwo image

So correct answer is :

Reagent 1: NaCN

Reagent 2: LiAlH4

Reagent 3: H2O
