Question

what are the physical properties of carbon compound or covelent compounds?​

Answer 1

ORGANIC COMPOUNDS & COVALENT COMPOUNDS:

It should be noted that all organic compounds are COVALENT but all covalent compounds are not ORGANIC. Covalent compounds may be made up of carbon atoms or may be not made up of carbon atoms. Examples of covalent compounds are HCl, NH3, CH4etc. The compounds of carbon are known as organic compounds. Examples are CH4, CHCl3, CH3COOH etc.

Physical properties of carbon compounds or organic compounds:

Carbon compounds have low melting and boiling points because force of attraction between their molecules are not very strong.

Carbon compounds are non- conductors of electricity because they do not contains ions.

Most carbon compounds occur in all living things like plants and animals

Physical properties of covalent compounds:

Covalent compounds are usually liquids or gases. Only some of them are solids. Covalent compounds are liquids and gases due to the weak force of attraction between their molecules.

Covalent compounds have usually low melting and boiling points because only a small amount of heat energy is required to break the weak molecular forces.

Covalent compounds are usually insoluble in water but they are soluble in organic solvents.

Covalent compounds do not conduct electricity means they are non- electrolytes because they do not contains ions.

Carbon compounds are organic and covalent compounds. But it also should be noted that all carbon compounds are not organic. Example of non- organic carbon compounds are CO2, CaCO3, NaHCO3 etc.

Answer 2

Answer_

Covalent compounds:

Covalent compounds are the ones having strong intra-molecular bonds. This is because the atoms within the covalent molecules are very tightly held together. Each molecule is indeed quite separate and the force of attraction between the individual molecules in a covalent compound tends to be weak.

• Carbon compounds have low melting and boiling points because force of attraction between their molecules are not very strong.
• Carbon compounds are non- conductors of electricity because they do not contains ions.
