anhydride?
Which of the following is a nitric acid
anhydride?
Updated On: Jun 21, 2024
- NO
- $NO_2$
- $N_2O_5$
- $N_2O_3$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Dinitrogen pentaoxide (N20 5) is prepared by
dehydrating the concentrated nitric acid with
phosphorus pentoxide.
$4HNO_3 + P_4O_10 \longrightarrow 2N_2O_6 + +HPO_3$
So, $N_2O_5$ is regarded as anhydride of $HNO_3$.

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
