Draw the lewis structure molecular geometry, electron geometry, hybridization of the central atom and determine if they are polar or nonpolar of molecules, of the compound bro3-
Accepted Answer
## BrO3- Lewis Structure, Geometry, and Polarity
1. Lewis Structure:
Count valence electrons: Br (7) + O (6 x 3) + 1 (negative charge) = 26 valence electrons
Connect atoms: Br is the central atom, single bonds to each oxygen atom.
Complete octets: Each oxygen needs 2 more electrons, and bromine needs 2 more. This uses up 24 electrons.
Place remaining electrons: The remaining 2 electrons go on bromine as a lone pair.
2. Molecular Geometry:
Electron Geometry: Tetrahedral (4 electron groups around Br)
Molecular Geometry: Trigonal Pyramidal (3 bonding pairs and 1 lone pair around Br)
3. Hybridization:
The central bromine atom has four electron groups (3 single bonds and 1 lone pair), so its hybridization is sp3.
4. Polarity:
BrO3- is polar. The trigonal pyramidal shape and the lone pair on bromine create an uneven distribution of electron density, resulting in a dipole moment.
