identify Z in sequence
`CH_(3)COONH_(4)overset((i)Heat)underset((ii)P_(2)O_(5))rarrYoverset(H_(2)O^(H^(+)))rarrZ`

Options

A. `CH_(3) - CH - underset(O)underset(||)(C ) - NH_(2)`
B. `CH_(3)` CN
C. `CH_(3)`COOH
D. `(CH_(3) CO )_(2)` O

Answer

C

Explanation

`CH_(3) CO bar(O)NH_(4)^(+) underset(2. P_(2) O_(3))overset(1. "heat") (rarr) CH_(3) - C equiv N underset(Delta)overset(H_(2)O //H^(oplus))(rarr) CH_(3) - "COOH" + NH_(3)`
