Why is H3PO2 basicity 1?
Basicity of H3PO2 depends on upon the number of ionizable -OH groups present in the molecule. That is the number of hydrogen attached to the electronegative atom oxygen. H3PO2 has one ionizable –OH group, thus its basicity is 1.
What is the basicity of a H3PO4 B H3PO2 and why?
In this compound, three hydrogen atomsS is joined with three oxygen atomsS. Therefore, the value of basicity is 3.
What is the basicity of H 3 PO 3 and why?
It has two P−OH bonds and one P−H bond. Hence, its basicity is 2. Here it is attached to 2 oxygen Hence basicity of H3PO3 is 2.
Is H3PO2 an acid or base?
Salts derived from this acid are called hypophosphites. HOP(O)H2 exists in equilibrium with the minor tautomer HP(OH)2. Sometimes the minor tautomer is called hypophosphorous acid and the major tautomer is called phosphinic acid….Hypophosphorous acid.

What is the basicity of H 3 BO 3?
Answer: Explanation:H3BO3 is boric acid. Boric acid dissociates weakely in water, but it is acidic due to its interaction with water to form tetrahydoxyborate ion. it is monobasic Lewis acid of boron, its basicity is 1, because it has capacity to give 1 H+ ion.
What is normality of 2M H3PO2 solution?
Normality of 2M H3PO2 is 2N.
What is the basicity of H 3 PO 5?
The basicity is defined as the number of hydrogen atom replaceable by a base in a particular acid. H3PO4 has three ionizable hydrogen atoms. Hence, its basicity is 3….The p-Block Elements.

What is the basicity of H 3 PO 4?
3
Basicity means number of replaceable hydrogen atoms. H3PO4 3H+ + PO4- For hydrogen to be acidic it must be attached to strong electronegative atom. Here it is attached to 3 oxygen Hence basicity of H3PO4 is 3.
Why is H3PO2 more acidic?
H3PO4> H3PO3> H3PO2. In the first case all the hydrogen atoms are attached to oxygen atom as OH group from which hydrogen can be easily released as protons. Hence,the acidity will be the highest.
Is H3PO2 a strong acid?
H3PO2 is a weak monobasic acid.
Why is H3PO2 a reducing character?
Originally Answered: Why does H3PO2 behave as reducing agent? Two P – H bonds are present in the hypophosphorus acid. Hence, it behaves as a reducing agent. In presence of H3PO2, AgNO3 is reduced to silver metal.
What is meant by the basicity of H3PO3?
Basicity means a number of replaceable hydrogen atoms. Basicity of the molecule is the number of acidic hydrogen atoms. To be acidic, hydrogen must be bound to a highly electronegative atom such as oxygen or fluorine. H 3 PO 3 is called orthophosphorous acid or phosphorous acid. It is one of the phosphorus oxygenic acids.
How many replaceable hydrogen atoms are present in H3PO2?
Basicity of an acid is the no. of replaceable hydrogen atoms.ie. the hydrogen atom attached to an oxygen atom. In H3PO2, 2 H-P bonds,1 P=O bond and 1 “P-O-H bond” is present. Thus,1 replaceable hydrogen atom (the one attached to oxygen atom) is present.
How do you find the basicity of a compound?
To find the basicity of the given chemical compound first let us know what the term basicity means. Basicity means a number of replaceable hydrogen atoms. Basicity of the molecule is the number of acidic hydrogen atoms. To be acidic, hydrogen must be bound to a highly electronegative atom such as oxygen or fluorine.
