Question

Assertion (A): Carbon shares its valence electrons with other atoms of carbon or with atoms of other elements.

Reason (R): The shared electrons belong to the outermost shells of both the atoms and lead to both atoms attaining the noble gas configuration.

विकल्प

• Both, Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

• Both, Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (А).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Both, Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

Explanation:

Carbon forms covalent bonds by sharing its valence electrons with other atoms. This sharing involves the outermost-shell electrons and helps atoms achieve a stable noble-gas configuration (octet).
Thus, the Reason correctly explains why carbon shares electrons.
