Type of solid: Molecular

1/4

How can you identify a molecular solid?

2+ non-metals bonded together

(can be same of the non-metal)

Examples of Molecular solid

H20,CO2,CH2CI2, C6H12

what is the bonding of molecular solids

strong intramolecular covalent bonds

weak intermolecular forces

Hardness of molecular solids

Generally soft and scrath easily, due to the weak intermolecular forces holding the molecules together.

they are so weak so they can be broken easily

melting/boiling point of molecular solid

GENERALLY LOW.

most are liquids or gasses at room temperature

this is due to the weak intermolecular forces holding the molecules together.

becauset hey are weak it takes very little energy to break them

when they are broken it causes a state change, hence a low (little energy) melting/boiling point.

Electrical conductivity of molecular solids?

NO ELECTRICAL CONDUCTIVITY.

they consist of only molecules with no charged particles which are free to move,

charged particles is something that is required for electrical conductivity.

Soluability of molecular solids?

Depends on the polarity.

polar substances generally soluable in poler solvents

non-polar substances are soluable in non-polar solvents.

Why does this law of soluability work for molecular solids?

The force of attraction between solute and solvent are strong enough to overcome the solute-solute and solvent-solvent bonds.

what particles make up molecular solids

molecules
