Question

Define Covalent compound.

Answer 1

Hint: The atoms in a molecule are going to stay together with an invisible force called a bond. The bond which is supposed to be present in between the chemical elements in the molecule then is called chemical bond.

Complete answer:
- In the question it is given to write the definition of the covalent bond.
- First, we should know about the chemical bond and types of chemical bond to know about the covalent bond in detail.
- The bond which is going to hold the atoms in molecules is called chemical bond.
- There are different types of chemical bonds which are present in different types of molecules.
- The type of chemical bond is going to depend on the electronegativity difference between the atoms.
- If the difference between the electronegativities of the atoms in the molecule is greater than 2.5 then the bond which is going to form in between the atoms will be an ionic bond.
- If the difference in electronegativity of the atoms is less than 2.5 then the bond which is going to be formed in between the atoms will be a covalent bond.
- In an ionic bond the electrons are going to be accepted by one of the atoms and in a covalent bond the electrons are going to be shared in between the atoms in the molecule.
- The compound which is going to have only covalent bonds in the entire molecule then the compound is called covalent compound.

Note:
The organic compounds are going to have only covalent bonds in their structures. Because in organic compounds the sharing of electrons is going to take place in between the atoms of the molecules.
