NEET2022ChemistryChemical Bonding and Molecular StructureActual
The correct order of bond angles in the following compounds/species is :
Options
- AH ₂ O < NH ₃ < + NH ₄ < CO ₂
- BH ₂ O < + NH ₄ < NH ₃ < CO ₂
- CH ₂ O < + NH ₄ = NH ₃ < CO ₂
- DCO ₂ < NH ₃ < H ₂ O < + NH ₄
Correct answer
A. H ₂ O < NH ₃ < + NH ₄ < CO ₂
Step-by-step solution
According to VSEPR theory, bond angle decreases with increase in lone pair, for molecules of same hybridisation. With increase in s-character, bond angle increase. order of bond angle =
