Question

1. list some of the properties of covalent compounds.

Explanation:

Covalent compounds are formed by sharing electrons. Key properties include: low melting/boiling points (due to weak intermolecular forces), poor electrical conductivity (no free ions/electrons), often insoluble in water (except polar covalent like ethanol), and exist as gases/liquids/solids (e.g., $CO_2$ gas, $H_2O$ liquid, diamond solid). They have covalent bonds, and many are volatile with distinct molecular structures.

Answer:

Some properties of covalent compounds:

1. Low melting and boiling points (weak intermolecular forces).
2. Poor electrical conductivity (no free ions/electrons to conduct).
3. Often insoluble in water (except polar covalent compounds like ethanol).
4. Can exist as gases (e.g., $CO_2$), liquids (e.g., $H_2O$), or solids (e.g., diamond).
5. Formed by covalent bonding (electron sharing between atoms).
6. Many are volatile (easily vaporize).
7. Have distinct molecular structures (e.g., molecular or network - like in diamond).
