Question

which of the following best describes all the intermolecular forces exhibited by a pure sample of CH3 CL? (a) dispersion only(b) dipole dipole and hydrogen bonding (c) dispersion and dipole dipole(d)dispersion and hydrogen bonding.

Answer 1

(a) dispersion only
 in the molecule of ch3cl

Answer 2

Answer:

The correct option is (c) Dispersion and dipole-dipole.

Explanation:

Dispersion

• In $CH_{3}Cl$, Cl being more electronegative pulls the electrons of C towards itself, developing a partial negative charge (δ⁻) on itself and a partial positive charge (δ⁺) on C.
• This creates a dipole.

• The partially positive charged (δ⁺) C will attract electrons of other molecules.

• This phenomena is called London dispersion force.

Dipole-dipole

• A $CH_{3}Cl$ dipole molecule will attract another $CH_{3}Cl$ dipole molecule.
• This phenomenon is called dipole-dipole force.

Conclusion:

The intermolecular forces in $CH_{3}Cl$ are dispersion and dipole-dipole.
