In the reaction,
`CH_(3)COOHoverset(L(A)H_(4))rarrAoverset(PC_(5))rarrBoverset(A//C.NOH)rarrC,` the product `C` is :-

Options

A. Ethylene
B. Acetyl chloride
C. Acetaldehyde
D. Acetylene

Answer

A

Explanation

`CH_(3)-overset(O)overset(||)C-OHoverset(LiAIH_(4))rarrCH_(3)overset((A))-CH_(2)-OHoverset(PCl_(5))rarr`
`CH_(3)overset((B))CH_(2)Cloverset(alc KOH)rarrCH_(2)overset((C))=CH_(2)`
Reduction of `CH_(3)COOH` will produce `CH_(3)-CH_(2)-OH(A)`
Now reaction of `CH_(3)-CH_(2)-OH(A)` with `PCl_(5)` will produce `CH_(3)-CH_(2)-Cl(B)`.
Now alcoholic KOH with `Et-Cl` will produce `CH_(2)=CH_(2)(C)` Ethylenen By `E_(2)` elemination Thus Ans. is (1) Ethylene.
