- Aldrin and Dieldrin
- Sodium chlorate and Aldrin
- Sodiumarsinate and Dieldrin
- Sodium chlorate and sodiumarsinite
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Aldrin and Dieldrin belong to the category of pesticides, while Sodium chlorate (NaClO3) and Sodium arsenite (Na3AsO3) fall into the category of herbicides.
So, the correct option is (D): Sodium chlorate and sodiumarsinite.

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
