Question

which of the following compund has highest boiling point​

Answer 1

Answer:

Explanation:

Can you please provide the options

Answer 2

Answer:

The correct answer is A.

Explanation:

A. Propionamide

The  

NH

2

group can form two hydrogen bonds, and the  

O

atom has two lone pairs available to form two more hydrogen bonds.

Thus, one molecule of propionamide can form a hydrogen bond to four other molecules,

B.  

N

-methylacetamide

The  

NH

group can form one hydrogen bond, and the  

O

atom has two lone pairs available to form two more hydrogen bonds.

Thus, one molecule of  

N

-methylacetamide can form hydrogen bonds to three other molecules,

C.  

N

,

N

-Dimethylacetamide and D. ethyl acetate

Neither compound has hydrogen bonding. The strongest intermolecular forces are dipole-dipole interactions.

Propionamide has the strongest intermolecular forces,

It should have the highest boiling point.
