Question:
Among the following oxides, the least acidic is
Among the following oxides, the least acidic is
Updated On: Jun 27, 2024
- $P_4O_6$
- $P_4O_{10}$
- $As_40_6$
- $As_4Ok$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Acidic character of oxides decreases down the group. Thus, oxides of As are less acidic than those of P. Acidic character increases with increase in oxidation state. Thus $AS_4O_{10}$ (O.S. = 5) is more acidic than $As_4O_6$ (O.S. = 3). Thus $ As_4O_6$ is least acidic

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
