**Statement 1:** Oxygen does not possess d-orbitals in its valence shell. **Statement 2:** The covalency of oxygen is two.

JEE Main Chemistry question

**Statement 1:** Oxygen does not possess -orbitals in its valence shell. **Statement 2:** The covalency of oxygen is two.

(A)Assertion is True, Reason is True; Reason is the correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not the correct explanation for AssertionCorrect
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (B)
