- Its monobasic nature
- Its geometry
Hide Solution
Verified By Collegedunia
The Correct Option is B
Approach Solution - 1
In Boric acid each B atom is $sp^2$ hybridized and contains $BO^{3-}_3$ units which are held together by hydrogen bonds.

The molecular formula for boron, hydrogen, and oxygen that makes up boric acid is H3BO3. It is a Lewis acid monobasic. Other names for boric acid include orthoboric acid, hydrogen borate, and acidum boricum.
The color of boric acid is a white powder. It dissolves fully in water. Borax and hydrochloric acid were combined to create it for the first time by Wilhelm Homberg. A substance of significant medical value called boric acid has a number of beneficial qualities, including antiviral, antifungal, and antiseptic.
The boron atom is located in the middle of the boric acid molecule. Three boron-oxygen single bonds between the boron atom and three hydroxyl groups make up the boric acid molecule. Boric acid has a trigonal planar structure.
There are three hydroxyl groups in boric acid. The OH bond is polar because of the difference in electronegativity between the oxygen and hydrogen atoms. As a result, the hydrogen from one molecule of boric acid creates a hydrogen bond with the oxygen atoms of another molecule of boric acid. A polymeric structure is created by the distinct layers of boric acid molecules. Covalent bonds are created between the hydrogen atoms and the BO3 group of another molecule.

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
