Question:
In compounds of type $EC1_3$, where E = B , P, As or Bi, the angles Cl-E - Cl for different E are in the order
In compounds of type $EC1_3$, where E = B , P, As or Bi, the angles Cl-E - Cl for different E are in the order
Updated On: Jun 14, 2022
- B > P = As = Bi
- B > P > As > Bi
- B < P = As = Bi
- B < P < As < Bi
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In BC13, bond angle = 120$^{\circ}$. In PC13, AsC13 and BiCl3, central atom is $sp^3$ hybridised. Since P, As and Bi are from the same group, bond angle decreases down the group. Hence, overall order of bond angle is : $ \, \, \, \, \, \, \, \, \, $ B > P > As > Bi

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
