In Hydrogen Bonding, Hydrogen Nearly Always Pairs With

Question

In hydrogen bonding, hydrogen nearly always pairs with:
A) another hydrogen.
B) carbon.
C) oxygen or nitrogen.
D) sodium or chlorine.

Accepted Answer

In hydrogen bonding, hydrogen atoms are attracted to electronegative atoms such as oxygen or nitrogen. This is because oxygen and nitrogen have a higher electronegativity than hydrogen, which allows them to form a partial negative charge and attract the partially positive hydrogen atom. Therefore, choice C (oxygen or nitrogen) is the best answer.
