Question:
The first ionisation potential of Na, Mg, Al and Si are in the
The first ionisation potential of Na, Mg, Al and Si are in the
Updated On: Aug 20, 2023
- Na < Mg >Al < Si
- Na > Mg > A1 > Si
- Na < Mg < Al > Si
- Na > Mg > Al < Si
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Ionisation energy increases from left to right in a period. However, exception occur between group 2 and group 13 elements on account of stability of electronic configuration of valence shell. $\Rightarrow $ The desired order is Na < Mg > A1 < Si

Haloalkanes and Haloarenes - Classification
Classification of Haloalkanes and Haloarenes are as follows:
Haloalkanes and Haloarenes are Classified on the Basis of the Number of Halogen Atoms:
These are further classified as mono, di, or polyhalogen (tri-,tetra-, etc.) compounds depending on whether they contain one, two or more halogen atoms in their structures. For example;
- Monohaloalkane
- Dihaloalkane
- Trihaloalkane
Haloalkanes and Haloarenes are Classified on Compounds Containing sp3 C—X Bond (X= F, Cl, Br, I)
This class includes:
- Alkyl halides or haloalkanes (R—X)
- Allylic halides
- Benzylic halides
Haloalkanes and Haloarenes are Classified on Compounds Containing sp2 C—X Bond
This class includes:
- Vinylic halides
- Aryl halides
