Maximum bond angle in CHF3, CHCl3, and CHBr3
Bond angle in CHF3, CHCl3, and CHBr3
The bond angle in a molecule is determined by the repulsion between its electron pairs. The greater the repulsion between the electron pairs, the larger the bond angle. In general, the bond angle decreases as the electronegativity of the halogen increases.
Bond angle in CHF3, CHCl3, and CHBr3
The bond angles in CHF3, CHCl3, and CHBr3 are tetrahedral. The bond angle in a tetrahedral molecule is 109.5°. However, the presence of lone pairs of electrons on the central atom can cause distortions in the bond angles.
Maximum bond angle in CHF3, CHCl3, and CHBr3
The maximum bond angle would be in the molecule with the least electronegative halogen. This is because the halogen with the least electronegativity will have the least repulsion with the electron pairs on the central atom.
Therefore, the molecule with the maximum bond angle would be CHBr3.
Conclusion
In conclusion, the bond angles in CHF3, CHCl3, and CHBr3 are tetrahedral, but the presence of lone pairs of electrons on the central atom can cause distortions in the bond angles. The maximum bond angle would be in the molecule with the least electronegative halogen, which is CHBr3.
