Dear user, acetic acid on reaction with phosphorous trichloride gives acetyl chloride which on reaction with ammonia gives acetamide and acetamide so form on reaction with lithium aluminium hydride gives ethylammine.

1. CH $_{}$ 3COOH $+$ PCl $_{}$ 3 $\to$ CH $_{}$ 3COCl

2. CH $_{}$ 3COCl $+$ NH $_{}$ 3 $\to$ CH $_{}$ 3CONH $_{}$ 2

3. CH $_{}$ 3CONH $_{}$ 2 $+$ LiAlH $_{}$ 4 $\to$ CH $_{}$ 3CH $_{}$ 2NH $_{}$ 2
