is less than the first ionisation potential of
B
The second ionisation potential of 
is greater than the second ionisation potential of 
is greater than the second ionisation potential of
C
The first ionisation potential of

is less than the first ionisation potential of
D
The third ionisation potential of 
is greater than the third ionisation potential of 
is greater than the third ionisation potential of
Text Solution
Verified by ExpertsThe correct answer is:
B
I.E.(II) of 
is higher than that of 
because in case of 
, the second 
has to be remove from the noble gas core while in case of 
removal of second 
gives a noble gas core.
has high first ionisation potential than 
because of its stable 
configuration.
