Question

what are covalent compound? why are they different from ionic compounds ?list their three characteristic properties.​

Answer 1

Answer:

Ionic CompoundsCovalent compounds1. These are usually crystalline solids.1. These are usually liquids or gases.2. They have high melting points and boiling points. i.e. these are non-volatile.2. These have low melting points and boiling points and are volatile.

Answer 2

Answer:

Covalent compounds are those compounds which are  formed by sharing of electrons between two atoms and  thus containing covalent bonds.

These compounds are different from ionic  compounds because the ionic compounds are formed  by the transference of electrons while covalent  compounds by sharing of electrons.

Characteristics of covalent compounds :

• They have generally low melting and boiling  points.
• They are generally insoluble or less soluble in  water but soluble in organic solvents like ethanol.
• They do not conduct electricity.
