NEETChemistryChemical Bonding and Molecular Structure
Although the geometries of NH 3 and H 2 O molecules are distorted tetrahedral, why is the bond angle in water less than that of ammonia?
Options
- AThe smaller size of oxygen atoms in H 2 O compared to nitrogen atoms in NH 3 leads to stronger repulsion betwe
- BWater molecules have a higher electronegativity than ammonia molecules, which results in stronger electron-ele
- CThe oxygen-hydrogen bond in H 2 O is weaker than the nitrogen-hydrogen bond in NH 3 , leading to a greater dis
- DThe presence of two lone pairs of electrons on the oxygen atom in H 2 O results in greater electron-electron r
Correct answer
D. The presence of two lone pairs of electrons on the oxygen atom in H 2 O results in greater electron-electron r
Step-by-step solution
Correct Option is : (D) The presence of two lone pairs of electrons on the oxygen atom in H 2 O results in greater electron-electron repulsion and a smaller bond angle compared to ammonia.
