Why do actual bond angles differ from the ideal bond angles? How does a lone pair of electrons affect bond angles?
Homework Answers
As the lone pair increases,then bond angle decreases. Because lone pair electrons repel the electron pair electrons.so bonds are slightly displaced inside hence bond angle decreases

9. How do the molecular geometry of the molecule IF5 and PF5 differ? A. In IF5, there is a lone pair of electrons on iodine where as in PF5 there are no lone pairs on phosphorus. As a result, the molecular shape of IF5 is square pyramidal and PF5 is trigonal bipyramidal. B. In PF5, there is a lone pair of electrons on phosphorus where as in IF5 there are no lone pairs on iodine. As a result, the molecular...

Why is the H–N–H angle in NH3 smaller than the H–C–H bond angle in CH4? The electron-pair geometry for NH3 is tetrahedral. with ______ bonding pair(s) of electrons and ______ lone pair(s) of electrons. A lone pair takes up more room than a single bond, causing the H–N–H angle to be smaller than the bond angle in a regular tetrahedron such as CH4. Why is the H–N–H angle in NH4+ identical to the H–C–H bond angle in CH4? The electron-pair...

Which of the following concerning electron pair space requirements and bond angles is/are incorrect? 1. Lone pairs of electrons require more space than bonding pairs. 2. Multiple bonds require the same amount of space as single bonds. 3. The HOH bond angle in H2O and the HNH bond angle in NH3 are identical because the electron arrangements (tetrahedral) are identical.
