Give 2 examples for each

1)Solid Covalent compounds

2)Gaseous Polar Compounds

3)Liquid Non polar Compounds

4) Gaseous Non Polar Compounds

Answer 1

1)Solid Covalent compounds

1. silicon dioxide, which has a giant covalent structure, so its melting temperature is very high
2. Diamond.
3. all sorts of plastics, where hundreds of small molecules join together to form a polymer

2)Gaseous Polar Compounds

• Ammonia (NH₃)
• Sulfur Dioxide (SO₂)

3)Liquid Non polar Compounds
->hydrocarbon oils,
->toluene
->chloroform.

4) Gaseous Non Polar Compounds

• carbon dioxide - CO₂
• benzene - C₆H₆
• carbon tetrachloride - CCl₄
• methane - CH₄
