Question

The incorrect statement among the following is
a) IE, of Al <I.E, of Mg
c) IE, of Na<I.E of Mg
b) I.E, of Mg > I.E, of Na
d) I.E of Mg > I.E, of Al​

Answer 1

Answer:

Correct option is

B

The second ionisation potential of Mg is greater than the second ionisation potential of Na

Second Ionization enthalpy I.E.2 of Na is higher than that of Mg because in case in Na, the second e−e- has to be removed from the noble gas core while in case of magnesium removal of second e−e- electron gives a noble gas core.

Option B is incorrect.
