Updated On: Aug 15, 2022
- $ {{H}_{2}} $
- $ Xe $
- $ C{{H}_{4}} $
- $ He $
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Boiling point $ \propto $ vander Waals force vander Waals force oc atomic mass (or molecular mass) $ \because $ Atomic mass of Xe is highest among. $ {{\text{H}}_{\text{2}}}\text{,He,}\,\text{C}{{\text{H}}_{\text{4}}}\text{,}\,\text{Xe} $ $ \therefore $ Boiling point of Xe is highest.

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
