JEE Mains · Chemistry · STD 12 - p -Block elements - ll
Given below are two statements:
Statement I: The covalency of oxygen is generally two but it can exceed upto four. The oxidation state of oxygen in \(SO_2\) is \(-2\) and in \(OF_2\) it is \(+2\).
Statement II: The anomalous behaviour of oxygen when compared to the other elements of group \(16\) is due to its small size and high electronegativity.
In the light of the above statements, choose the correct answer from the options given below
- A Both Statement I and Statement II are true
- B Both Statement I and Statement II are false
- C Statement I is true but Statement II is false
- D Statement I is false but Statement II is true
Answer & Solution
Correct Answer
(A) Both Statement I and Statement II are true
Step-by-step Solution
Detailed explanation
Statement I: The electronic configuration of oxygen is \(1s^{2} 2s^{2} 2p^{4}\). Due to the absence of d-orbitals, its maximum covalency is limited to four (using one 2s and three 2p orbitals). Its covalency is generally two, but it can exceed two and go up to four in certain…
