Question

A molecule contains hydrogen bonding if it contains hydrogen covalently bonded to

Answer 1

Answer:

Fluorine, oxygen, or nitrogen

Explanation:

Hydrogen bridge bond: It is an attraction that exists between a hydrogen atom (positive charge) with a very electronegative small atom, such as fluorine (F), oxygen (O) or nitrogen (N) (FH, OH, NH), which It has a pair of free electrons (negative charge), hence the name "hydrogen bond", which should not be confused with a covalent bond to hydrogen atoms). A hydrogen bridge is actually a dipole-dipole attraction between molecules that contain these three types of polar junctions.

This type of attraction has only a third of the strength of covalent bonds, but it has important effects on the properties of the substances in which they occur, especially in terms of melting and boiling points in crystal structures.
