Which of the following should be most volatile?
(I) 
(II) 
(III) 
(IV) 
Text Solution
Verified by ExpertsThe correct answer is:
B
The order of boiling points of isomeric amines is 
amines > 
amines > 
amines
Because of absence of H-atom available for hydrogen bonding, 
amines do not have intermolecular association. Intermolecular association is more in 
amines than in 
amines as there are two H-atoms available for H-bonding. hydrocarbons are almost non-polar molecules and possess weak van der Waals forces and hence has lowest boiling point i.e. most volatile.
