Question

Which statement best describes what happens during hydrogen bonding?
Hint: Think about the formation of hydrochloric acid (HCl) as an example of a compound with hydrogen bonding.

A. The partial negative hydrogen atom in one molecule and a partial positive atom in another molecule experience attraction.

B. The partial positive hydrogen atom in one molecule and a partial negative atom in another molecule experience attraction.

C. The partial positive hydrogen atom in one molecule and a partial positive atom in another molecule experience attraction.

D. The electronegative hydrogen atom in one molecule and a partial negative atom in another molecule experience attraction.

Answer 1

The best statement that describes what happens during hydrogen bonding, particularly in the context of hydrochloric acid (HCl) as an example, is:

**B. The partial positive hydrogen atom in one molecule and a partial negative atom in another molecule experience attraction.**

In hydrogen bonding, the hydrogen atom typically becomes partially positive due to its bond with a highly electronegative atom (like chlorine in HCl), and it is attracted to the partial negative charge of another electronegative atom in a different molecule.
