Question

`CH_(3)CH=CHCH(OH)CH_(3)rarrCH_(3)CH=CHCOCH_(3)` which of the following reagents should be used to bring about the above conversion?
A.
B. `H_(2)O_(2)//OH^(-)`
C. `KMnO_(4)//H_(2)SO_(4)`
D. `K_(2)Cr_(2)O_(7)//H_(2)SO_(4)`

Answer 1

Correct Answer - A
`PC C` (pyridinium chloromate) does not oxidize the double bond but oxidizes the `2^(@)` alcohol to ketone:
`CH_(3)CH=CHCH(OH)CH_(3)overset(PC C)(rarr)CH_(3)CH=CHCOCH_(3)`
