Questions asked by users might not always be phrased in the clearest way.
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 scn-
Accepted Answer
## SCN- Lewis Structure, Geometry, and Polarity
1. Lewis Structure:
Total Valence Electrons: S (6) + C (4) + N (5) + 1 (negative charge) = 16
Connecting Atoms: S-C-N
Octet Rule: Complete the octets of each atom by adding lone pairs and multiple bonds.
[Image of Lewis Structure: S=C=N with a single lone pair on S and two lone pairs on N]
2. Molecular Geometry:
Central Atom: Carbon (C)
Electron Groups: Two double bonds and no lone pairs on the central carbon.
Electron Geometry: Linear
Molecular Geometry: Linear
3. Hybridization:
The central carbon atom has two electron groups, resulting in sp hybridization.
4. Polarity:
SCN- is a polar molecule. While the carbon-sulfur and carbon-nitrogen bonds are both polar, the molecule is linear. The polarities of the bonds do not cancel out, resulting in a net dipole moment.
