Question

The major product formed in the reaction
`CH_(3)CH = CH - overset(O)overset(||)(C ) - CH_(3)underset(H_(2)O,CH_(3)OH)overset(NaBH_(4))rarr` is
A. `CH_(3)CH = CHCH(OH)CH_(3)`
B. `CH_(3)CH_(2)CH(OH)CH_(3)`
C. `CH_(3)CH_(2)overset(OH)overset(|)(CH)COCH_(3)`
D. `CH_(3)CH_(2)CH_(2)COCH_(3)`

Answer 1

Correct Answer - A
Sodium borohydride does not reduce the carbon-carbon double bond but reduces the ketone to secondary alcohol
`CH_(3)CH = CHCH(OH)CH_(3) underset(H_(2)O,CH_(3)OH) overset(NaBH_(4))larr`
`CH_(3)CH = CH -overset(O) overset(||)(C)-CH_(3)`
