Question

Hydrogen bonds form between molecules containing _________ bonds; the hydrogen bond is between a hydrogen atom of one molecule and a partially _________ charged atom of another.
A. polar covalent; negativelyB. polar covalent; positivelyC. nonpolar covalent; positivelyD. nonpolar covalent; negativelyE. ionic; positively

Answer 1

Answer:

The answer is A. Polar covalent; negatively

Explanation:

Hydrogen bonds form between molecules containing polar covalent bond the hydrogen bond is been a hydrogen atom of one molecule and a partially negative charged atom of another.

Example $H_{2}O$ (water):- It contain a slight positive charge on one side and a slight negative charge on the other.

Answer 2

The required words to fill the gap exist in Choice A. polar covalent; negatively.

Definition:

A hydrogen bond is simply as a result of an electromagnetic attraction created between a partially positively charged hydrogen atom attached to a highly electronegative atom and another nearby electronegative atom.

A hydrogen bond is a type of dipole-dipole interaction; it is not a true chemical bond as it occurs in molecules containing slightly polar covalent bonds.
