Explain why the covalent solids are usually soluble in non-polar solvents but are insoluble in polar solvents.

Explain why the covalent solids are hard.

Explain the following: Covalent solids are usually soft.

Explain why ionic solids are more soluble in polar solvents.

Explain why the covalent solids are bad conductors of electricity.

Explain the terms: solvent.

Non-polar molecule are:

Explain why ionic compounds are soluble in water but insoluble in organic solvents?

Give reasons for the following Electrovalent compounds are soluble in water, insoluble in organic solvents, good conductors of electricity in molten or aq.solution state, have high meltimg points and undergo electrolytic dissociation on pasaage of electric current, while covalent compounds are soluble in organic solvents, insoluble in water, non-conductors of electricity, have low melting points & undergo ionisation on passage of electric current.

Explain why very small animals are rarely found in polar region.

Assertion (A): Iodine is more soluble in C Cl_(4) than in water. Reason(R ): Non-polar solutes are more soluble in non-polar solvents.
