$H_3BO_3$ is
- monobasic acid and weak Lewis acid
- monobasic and weak Bronsted acid
- monobasic and strong Lewis acid
- tribasic and weak Bronsted acid
The Correct Option is A
Solution and Explanation
The correct option is(A): monobasic acid and weak Lewis acid.
H3BO3 (Boric Acid):
Monobasic Acid: Boric acid is a weak monobasic acid. This means it can donate one hydrogen ion (H+) per molecule when it reacts with water. However, its acidity is relatively weak compared to strong acids. It forms a relatively small number of hydrogen ions in solution.
Weak Lewis Acid: Boric acid is considered a weak Lewis acid. A Lewis acid is a species that can accept an electron pair from a Lewis base during a chemical reaction. In the case of boric acid, it has an empty p-orbital on the boron atom, which allows it to accept an electron pair from a Lewis base.
- Boric acid is a weak monobasic acid, capable of donating one hydrogen ion per molecule in water.
- Boric acid is a weak Lewis acid, as it can accept an electron pair from a Lewis base..

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
