The decreasing values of bond angles from NH3 (106º) to SbH3 (101...
The bond angle decreases on moving down the group due to decrease in bond pair-bond pair repulsion.
NOTE : This can also be explained by the fact that as the size of central atom increases sp3 hybrid orbital becomes more distinct with increasing size of central atom i.e. pure p- orbitals are utilized in M–H bonding

Explanation:
Electronegativity:
- The decreasing values of bond angles from NH3 to SbH3 down Group-15 of the periodic table can be attributed to the decreasing electronegativity of the central atom.
- Electronegativity is the ability of an atom to attract shared electrons towards itself in a covalent bond.
- As we move down the group from nitrogen to antimony, the electronegativity of the central atom decreases.
- This results in a weaker pull on the bonding electron pairs, leading to a larger bond angle.
Effect on Bond Angles:
- In NH3 (ammonia), nitrogen is more electronegative compared to antimony in SbH3 (antimony hydride).
- The greater electronegativity of nitrogen results in stronger electron pair-bond pair repulsions, leading to a smaller bond angle in NH3.
- As we move down the group, the decreasing electronegativity of the central atom reduces the repulsion between the lone pair and bond pairs, allowing for a larger bond angle in SbH3.
Conclusion:
- Therefore, the decreasing values of bond angles from NH3 to SbH3 down Group-15 of the periodic table are primarily due to the decreasing electronegativity of the central atom.
- This change in electronegativity affects the repulsion between electron pairs, leading to variations in bond angles across the group.
