State four properties each of electrovalent and covalent compounds.
Answers
Answer:
Electrovalent compounds are generally soluble in water and insoluble in solvents such as kerosene, petrol, etc.
Solubility.
They have high melting and boiling points. ...
Melting. ...
These are solids and are somewhat hard because of the strong force of attraction between the positive and negative ions. ...
Physical.
Explanation:
Properties of Covalent Molecular Compounds.
Low melting points and boiling points. ...
Low enthalpies of fusion and vaporization These properties are usually one or two orders of magnitude smaller than they are for ionic compounds.
Soft or brittle solid forms. ...
Poor electrical and thermal conductivity
The general properties of the covalent compounds are as follows:
Generally liquids or gases.
Usually low melting whenever they are solids.
Usually not very soluble in water.
Usually soluble in the organic solvents.
Non conductors of heat and electricity except they dissolve to form ions example: HCl.
