TS EAMCET · Chemistry · p Block Elements (Group 15, 16, 17 & 18)
Assertion (A): In group 15 elements nitrogen does not form pentahalides Reason (R): Nitrogen can exhibit +5 oxidation state The correct option among the following is
- A (A) and (R) are true. (R) is the correct explanation of (A)
- B (A) and (R) are true, but (R) is not correct explanation of \((\mathrm{A})\)
- C (A) is true but (R) is false
- D (A) is false but (R) is true
Answer & Solution
Correct Answer
(B) (A) and (R) are true, but (R) is not correct explanation of \((\mathrm{A})\)
Step-by-step Solution
Detailed explanation
Nitrogen is notable to form pentahalides as it does not have vacant d-orbitals available for expanding the octet. Thus, Assertion (A) is a correct statement. Nitrogen exhibits an oxidation state of +5 using all five of its valence electrons. Thus, reason (R) is a correct…
