Q1 of 33 Page 223

Assertion: Chemical bonds in organic compounds are covalent in nature.

Reason: Covalent bond is formed by the sharing of electrons in the bonding atoms.


Does the reason satisfy the given assertion?


Yes, the reason satisfies the given assertion.

Explanation: The carbon atom has:


i. Atomic number = 6


ii. Electronic configuration = 2,4



iii. Four electrons in the outermost shell


To achieve noble gas configuration (2,8) carbon atom shares its valence electrons (electrons in the outermost shell) with other atoms of carbon or with atoms of other elements.


In the covalent bond, sharing of electrons takes place. For


example: CH4
