The correct sequence of decrease in the bond angles of the following hydrides is
Updated On: Jul 7, 2022
- $NH_3 > PH_3 > AsH_3 > SbH_3$
- $NH_3 > AsH_3 > PH_3 > SbH_3$
- $SbH_3 > AsH_3 > PH_3 > NH_3$
- $PH_3 > NH_3 > AsH_3 > SbH_3$
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
In similar molecules, as the electronegativity of the central atom decreases and the size increases, the bond angle decreases

Group 15 Elements
Group 15 elements are also known as nitrogen group elements or nitrogen family.
It consists of:
- Nitrogen (N)
- Phosphorus (P)
- Arsenic (As)
- Antimony (Sb)
- Bismuth (Bi)
- Moscovium (Mc)
They are present on the right side of the periodic table. All the elements are arranged based on their atomic weight. The elements with similar properties reside in a column called the group.
All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is the principal quantum number.
