The decreasing order of boiling points of
ethyldimethylamine, n- butylamine and diethylamine is n – Butylamine > Diethylamine > ethyldimethylamine. This trend of boiling poit can be explained as.
A
Boiling point increases with increase in molecular mass.
B
Tertiary amines have highest boiling point due to highest basicity.
C
Intermolecular hydrogen bonding is maximum in primary amines and absent in tertiary amines
D
Intramolecular hydrogen bonding is present in tertiary amines.
Answer
Intermolecular hydrogen bonding is maximum in primary amines and absent in tertiary amines
Explanation
Solution
: The trend in boiling point can be explained on the basis of intermolecular hydrogen bonding which is maximum in primary amines.
