Answer to Question #118448 in Chemistry for Angelina

Question

Which of the following is true?

Hydrogen bonds are stronger than covalent bonds.
A hydrogen bond is an electrostatic attraction between the nucleus of a hydrogen atom, bonded to fluorine, oxygen, or nitrogen, and the positive end of a nearby dipole.
In liquid water, each water molecule is hydrogen bonded to two other water molecules.
Hydrogen bonding is one type of dipole-dipole interaction

Answer 1

Hydrogen bonding is one type of dipole-dipole interaction. This statement is true. Dipole-dipole interactions are forces that occur between partial charges of molecules that have uneven distribution of electrons and are polar. As water molecules are polar and have partially positive (hydrogen) and partially negative (oxygen) charges, they are involved in dipole-dipole interactions called hydrogen bonds.
