Vedclass · Answer

(C) The bond angle in these molecules depends on the electronegativity of the halogen atoms attached to the central carbon atom.As the electronegativity of the halogen atom decreases,the bond pair electrons are pulled less towards the halogen,resulting in greater repulsion between the bond pairs around the central atom.Electronegativity order: $F > Cl > Br$.Therefore,the bond angle increases as the electronegativity of the halogen decreases.The order of bond angles is: $CHF_3 Thus,$CHBr_3$ has the maximum bond angle.
