Assertion (A) : The ionisation energy of N is more than that of O
Reason (R ) : Electronic configuration of N is more stable due to half - fillied `2p` orbitals

Options

A. If both (A) and (R ) correct and (R ) is the correct explanation for (A)
B. If both (A) and (R ) correct and (R ) is the correct explanation for (A)
C. If (A) is correct but (R ) is incorrect
D. If (A) is incorrect but (R ) is correct

Answer

A

Explanation

N has electronic configuration `= 1s^(2) 2s6(2)3s^(2)3p^(3)`
O has electronic configuration `= 1s^(2) 2s6(2)3s^(2)3p^(6)`
N is stable due to half -filled p obtained .
