In which of the following options, the molecules are correctly arranged in the increasing order of their bond angles?
Show Hint
VSEPR Theory General Rules for Bond Angles:
1. Start with the ideal angle based on the number of electron domains (Linear: 180°, Trigonal Planar: 120°, Tetrahedral: 109.5°).
2. Lone pair - lone pair repulsion>lone pair - bonding pair repulsion>bonding pair - bonding pair repulsion.
3. Lone pairs and multiple bonds occupy more space than single bonds and thus compress the angles between other bonds.
