A compound with the formula `C_(4)H_(10)O` yields another compound `C_(4)H_(8)O`, on heating with `K_(2)Cr_(2)O_(7)` and `H_(2)SO_(4)`. The compound `C_(4)H_(10)O` is expected to be

Options

A. `CH_(3)CH_(2)CHOHCH_(3)`
B. `CH_(3)CH_(2)CH_(2)CH_(2)OH`
C. `(CH_(3))_(2)CHCH_(2)OH`
D. `(CH_(3))_(3)C-OH`

Answer

A

Explanation

`underset((C_(n)H_(2n+2)O))(C_(4)H_(10)O)overset([O])(rarr)underset((C_(n)H_(2n)O))(C_(4)H_(8)O)`
The general formula, `C_(n)H_(2n+2)O`, corresponds to a monohydric alcohol. A `1^(@)` alcohol is oxidized to a carboxylic acid `(C_(n)H_(2n)O_(2)),2^(@)` alcohol is oxidized to a keton e`(C_(n)H_(2n)O)` while `3^(@)` alcohol is oxidized to a mixture of ketone and acid, each contaning fewer carbon atoms than the original alcohol
`CH_(3)CH_(2)underset((C_(4)H_(10)O))(CH)(OH)CH_(3)overset([o])(rarr)underset((C_(4)H_(8)O))(CH_(3)CH_(2)COCH_(3))`
