D) \[Na\text{ }<\text{ }Al\text{ }<\text{ }Mg\text{ }<\text{ }Si\]
Correct Answer: D
Solution :
Generally, ionisation potential increases, as we move from left to right in a period. However, the ionisation potential of II group elements is higher than that of the III group elements. This is because of the fully filled s-orbitals in II group elements. Hence, the correct order of ionisation potential is Na < Al < Mg < SiYou need to login to perform this action.
