Identify the product 'Z' in the following sequence of reactions.
`CH_(3)CNoverset(Na+C_(2)H_(5)OH)rarr Xoverset(HNO_(2))underset(H_(2)O)rarrYoverset(K_(2)Cr_(2)O_(7))underset(H_(2)SO_(4))rarr Z`

Options

A. `CH_(3)CHO`
B. `CH_(3)CONH_(2)`
C. `CH_(3)COOH`
D. `CH_(3)CH_(2)NHOH`

Answer

C

Explanation

`CH_(3)- C -= N underset("Reduction")overset(Na+ EtOH)rarr CH_(3)- CH_(2) - NH_(2) overset(HNO_(2))rarr CH_(3)CH_(2)- OH underset(H_(2)SO_(4))overset(K_(2)Cr_(2)O_(7))rarr CH_(3)COOH`
