An optically active amine (A) of molecular formula C_(4)H_(11) N is subjected to Hofmann 's exhaustive methylation process and following hydrolysis an alkene (B) is produced which upon ownolysis and subsequent hydrolysis yields fonnaldehyde and propanal. The amine 'A' is

Answer»

`underset(NH_(2))underset(|)(CH_(3)CHCH_(2)CH_(3))`
`underset(CH_(3))underset(|)(CH_(3)NH-CH-CH_(3))`
`underset(CH_(3))underset(|)(CH_(3)-NH_(2)CH_(3))`
`underset(CH_(3))underset(|)(CH_(3)CH_(2)CH_(2)CHNH)`

SOLUTION :The optically ACTIVE molecute is
`CH_(3)-CH_(2)-underset(NH_(3))underset(|)(CH)-CH_(3)`
