Question

Hydrogen bonding is responsible for:

a. the unexpectedly high boiling points for binary molecular hydrides (XHn) in period two
b. the increasing boiling points for binary molecular hydrides (XHn) going down a group
c. the low boiling points of nonpolar molecules
d. none of the above

Answer 1

Answer:

a. the unexpectedly high boiling points for binary molecular hydrides (XHn) in period two

Explanation:

Hydrogen bonding is understood as the bond and all the results due to the bonding between hydrogen any any of oxygen, nitrogen and flourine which are all found in period two. Where this bond exists, especially binary molecular hydrides, the molecular substance tends to have a higher than expected boiling point.
