The correct order of first ionization enthalpy for the given four elements is :

1. C < F < N < O
2. C < N < F < O
3. C < N < O < F
4. C < O < N < F

If first ionization enthalpies of elements X and Y are 419 kJ mol-1 and 590 kJ mol-1, respectively and second ionization enthalpies of X and Y are 3069 kJ mol-1 and 1145 kJ mol-1, respectively. Then correct statement is :

1. Both X and Y are alkaline earth metals
2. X is an alkali metal and Y is an alkaline earth metal
3. X is an alkaline earth metal and Y is an alkali metal
4. Both X and Y are alkali metals

Identify the incorrect match.

1. (b)-(ii)
2. (c)-(iii)
3. (d)-(iv)
4. (a)-(i)

3. (A)-(iv), (B)-(iii), (C)-(ii), (D)-(i)
4. (A)-(i), (B)-(ii), (C)-(iii), (D)-(iv)

For the second period elements the correct increasing order of first ionization enthalpy is :

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