Which of the following will give yellow precipitate with `l_(2)//NaOH`?

Options

A. `CH_(3)-CO-O-CO-CH_(3)`
B. `I-CH_(2)-overset(O)overset(||)C-CH_(2)-CH_(3)`
C. `CH_(3)-CO-NH_(2)`
D. `CH_(3)-overset(OH)overset(||)C-CH_(2)-CH_(3)`

Explanation

`lCH_(2)-CO-CH_(2)-CH_(3)` on further treatment with `l_(2)//NaOH` first give `l_(2)CHCOCH_(2)CH_(3)` and then `l_(3)C-CO-CH_(2)-CH_(3)` which subsequently undergoes hydrolysis with NaOH to yield `CHl_(3)andCH_(3)-CH_(2)-COOHNa`.
`CH_(3)-overset(OH)overset(||)C-CH_(2)-CH_(3)` being methyl carbinol on treatment with `l_(2)//NaOH` will also give `CHl_(3)`.
