NEETChemistryp 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
Options
- 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 ( A )
- C(A) is true but (R) is false
- D(A) is false but (R) is true
Correct answer
B. (A) and (R) are true, but (R) is not correct explanation of ( A )
Step-by-step solution
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 statement. The Reason (R) is not a correct explanation of the Assertion (A).
