Theisomerof C_(5) H_(13) N'A on reaction withnitrousacid gives-2- Methyl-2- butanolthe isomer 'B'on reactionwithacetyl chloridegives N- ethyl-N-isopropylacetamide Whereas isomer'C'have noreactionwith aceticanhydridewhich of thefollowingare A, B and C ?

Answer»

2-methyl -2- butanamineN-ethyl-2- PROPANAMINE N-ethyl - N- methylehtanamine
2-Methyl -1- butanamine N- ethyl -2-propanamine andN,N- dimethyl ethanamine
2-methyl - 1-butanamineN- ethyl-2-propanamineand N,N- dimethyl ethanamine
20 Methyl- 2- butanamineN- methyl-2-butanamineand N- ethyl -N- methylethanamine

Solution :`CH_(3)- overset(CH_(3)) overset(|)underset(NH_(2)) underset(|) (C ) -CH_(2) CH_(3)+ HNO_(2) to CH_(3)- overset( CH_(3))overset(|)underset( OH) underset (|) ( C ) - CH_(2)- CH_(3)`
Isomer A(Primaryamine )
`CH_(3)- underset( CH_(3) ) underset(|) (CH) -NH -C _(2) H_(5) +CH_(3) COCI to `
`CH_(3) - underset( CH_(3))underset(|)(C H)- overset(COCH_(3)) overset(|) (N)- C_(2) H_(5)`
Isomer B(Secondaryamine)
`C_(2) H_(5)-underset( CH_(3) ) underset(|)( N) - C_(2)H_(5) +(CH_(3) CO )_(2)O to` Noreaction
