Question: The correct order of boiling points of the following isomeric amines is. \(C_{4}H_{9}NH_{2},\left( ...

The correct order of boiling points of the following isomeric amines is.

C4H9NH2,(C2H5)2NH,C2H5(CH3)2C_{4}H_{9}NH_{2},\left( C_{2}H_{5} \right)_{2}NH,C_{2}H_{5}\left( CH_{3} \right)_{2}

A

C2H5N(CH3)2>(C2H5)2NH>C4H9NH2C_{2}H_{5}N\left( CH_{3} \right)_{2} > \left( C_{2}H_{5} \right)_{2}NH > C_{4}H_{9}NH_{2}

B

(C2H5)2NH>C2H5N(CH3)2>C4H9NH2\left( C_{2}H_{5} \right)_{2}NH > C_{2}H_{5}N\left( CH_{3} \right)_{2} > C_{4}H_{9}NH_{2}

C

C4H9NH3>(C2H5)2NH>C2H5N(CH3)2C_{4}H_{9}NH_{3} > \left( C_{2}H_{5} \right)_{2}NH > C_{2}H_{5}N\left( CH_{3} \right)_{2}

D

(C2H5)2NH>C4H9NH2>C2H5N(CH3)2\left( C_{2}H_{5} \right)_{2}NH > C_{4}H_{9}NH_{2} > C_{2}H_{5}N\left( CH_{3} \right)_{2}

Answer

C4H9NH3>(C2H5)2NH>C2H5N(CH3)2C_{4}H_{9}NH_{3} > \left( C_{2}H_{5} \right)_{2}NH > C_{2}H_{5}N\left( CH_{3} \right)_{2}

Explanation

Solution

: The boiling point of amines vary in the order of primary > secondary > tertiary.
