To convert alkyl halide to primary amine we use:
KCN followed by LiAlH4
Methanal
Catalytic reduction
Ethanoic acid
For converting alkyl halides into primary amines having one carbon atom more than the parent alkyl halides, we use KCN followed by LiAlH4.
By the reduction of alkyl halides, we get alkanes. The best alkyl halide is
