Solution

Q.
For elements B, C, N, Li, Be, O and F, the correct order of first ionization enthalpy is [2023]

1 Li < Be < B < C < O < N < F

2 Li < Be < B < C < N < O < F

3 Li < B < Be < C < O < N < F

4 B > Li > Be > C > N > O > F

Ans.
(3)

The correct increasing order of first ionization enthalpies is

Li < B < Be < C < O < N < F

Li – 520 kJ/mol
Be – 899 kJ/mol
B – 801 kJ/mol
C – 1086 kJ/mol
N – 1402 kJ/mol
O – 1314 kJ/mol
F – 1681 kJ/mol
