Question:
$B(OH)_3$ is a
$B(OH)_3$ is a
Updated On: Jun 6, 2022
- Lewis acid
- Lewis base
- Bronsted base
- Bronsted acid
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Lewis acids are the electron-pair acceptor and bases are the electron-pair donor. Bronsted acids give proton whereas bases accept proton. Boric acid or orthoboric acid $\left( H _{3} BO _{3}\right.$ or $\left. B ( OH )_{3}\right)$ can accept a pair of electrons from Lewis bases and hence, act as Lewis acid.

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
