B. Chlorine
C. Sodium chloride
D. Water

Answer 1

Answer:

c is the real and:69dehati6ex

Answer 2

Final answer: B. Chlorine

Given that: We are given Ammonium chloride, Chlorine, Sodium chloride, Water.

To find: We have to find which one have Van der waals' forces are dominant intermolecular force.

Explanation:

• Van der waals' forces are the attractive or cohesive inter molecular forces. There are several types of attractive forces work in a given pair of molecules. Three main types of attractive forces are,

1. Dipole-diploe forces which is interaction between polar molecules.

2. Dipole- induced dipole forces also known as Debye forces which is attractive forces between polar molecules and nonpolar molecules.

3. Induced dipole–induced dipole force also known as London forces which is interaction between atoms or non-polar molecules.

• The Van der waals' forces are dominant intermolecular forces in Chlorine.
• Ammonium chloride is formed through three covalent bonds, one coordinate bond, and one bond between N atom and one H atom. Hence weak intermolecular force present. Is an ionic compound.

• Intermolecular force present in sodium chloride NaCl is ion- ion forces which is intermolecular interaction between opposite charged ions. Na⁺ and Cl⁻. So dipole-dipole force are the dominant intermolecular forces in NaCl.

• Intermolecular force present in water is hydrogen bond, its a special type of dipole-dipole interaction between molecules.
