Which of the following oxidation reaction can be carried out with chromic acid in aqueous acetone at 5 - 10(@) C?

Answer»

`CH_(3)(CH_(2))_(3)C-=C-underset(OH)underset(|)(CH)-CH_(3)to CH_(3)(CH_(2))_(3)-=C-overset(O)overset(||)(C)-CH_(3)`
`CH_(3) (CH_(2))_(3) CH = CH - CH_(2) OH rarr CH_(3) (CH_(2))_(3) CH =CH - CHO`
`C_(6) H_(5) CH_(3) rarr C_(6) H_(5) COOH`
`CH_(3) (CH_(2))_(3) CH_(2) OH rarr CH_(3) (CH_(2))_(3) CHO`

Solution :`1(@)` Primary alcohol `overset(ZnCL_(2)//HCl) to`
WHITE turbidty only heating
`2(@)` Alcohol `overset(ZnCL_(2)//HCl) to` White turbidty after `5 min` heating
`3(@)` Alcohol `overset(ZnCL_(2)//HCl) to` easily in seconds
