Question

Classify each substance based on the intermolecular forces present in that substance.
A. Hydrogen bonding, dipole dipole, and dispersion
B. Dipole dipole and dispersion only
C. Dispersion only
1. H2O
2. CH4
3. CO
4. CH2Cl

Answer 1

Answer:

H2O- Hydrogen bonding, dipole dipole, and dispersion

CH4- Dispersion only

CO- Dispersion only

CH2Cl- Dipole dipole and dispersion only

Explanation:

Dipole- dipole interactions exist only in molecules that have a dipole moment such as water and dichloromethane. Water experiences intermolecular hydrogen bonding in addition to dipole-dipole interaction and dispersion forces due to the O-H bond in the molecule.

Nonpolar compounds only have dispersion forces acting between its molecules.

Answer 2

               Intermolecular forces

1. When H2O- Hydrogen bonding, dipole-dipole, and also dispersion
2. Then CH4- Dispersion only
3. After that CO- Dispersion only
4. Then CH2Cl- Dipole-dipole and also dispersion only

Explanation:

• When Dipole-dipole interactions exist only in molecules that have a dipole moment such as water and also that dichloromethane.
• After that Water experiences intermolecular hydrogen bonding in addition to dipole-dipole interaction and also that dispersion forces due to the O-H bond in the molecule.
• Thus, Nonpolar compounds only have dispersion forces acting between their molecules.
