The ionization enthalpy will be highest when the electron is to be removed from .............. if other factors are equal :
A
s-orbital
B
p-orbital
C
d-orbital
D
f-orbital
Answer
s-orbital
Explanation
Solution
The increasing order of 1st ionisation energy is f < d < p < s because of the increasing order of the penetration of the electrons as f < d < p < s if all other factors are same.
