Which statement is incorrect about the nature of the hydrogen bond?



A. The donor is a hydrogen atom bonded to a less electronegative atom than hydrogen.
B. The more linear the bond, the stronger the interaction.
C. The acceptor is a fairly electronegative atom containing a nonbonding pair of electrons.
D. It is a type of noncovalent bond.

A hydrogen bond occurs when a more electronegative atom such as fluorine (F), nitrogen (N), or oxygen (O), is attracted to hydrogen (H). Any atoms that are less electronegative than hydrogen cannot form a hydrogen bond. When a hydrogen atom is bonded with another hydrogen atom, the bond they form is call intramolecular bond.

Intermolecular on the other hand is when hydrogen bonds with a different kind of atom. Not all hydrogen bonds have the same strength. An HO−H···:OH+3 has a 4.3 kcal.mol strength while the F−H···:F has 38.6 kcal/mol bonding strength. The hydrogen may be the proton acceptor or donor depending if the electronegative atom is covalently bonded or not to it.
