Choose the weak monobasic acid, among the following
Updated On: Jun 4, 2024
- $H_3BO_3$
- $H_3PO_3$
- $H_3PO_4$
- $HNO_3$
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
$H _{3} BO _{3}$ is a weak Lewis monobasic acid, because it can only accept a pair of electron. None of its hydrogens are ionisable.
Note $H _{3} PO _{3}$ is a dibasic acid, $H _{3} PO _{4}$ is a tribasic acid, $HNO _{3}$ is a strong monobasic acid and $H _{4} P _{2} O _{7}$ is a tetrabasic acid.
Note $H _{3} PO _{3}$ is a dibasic acid, $H _{3} PO _{4}$ is a tribasic acid, $HNO _{3}$ is a strong monobasic acid and $H _{4} P _{2} O _{7}$ is a tetrabasic 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
