The molecular structure of the molecule sulfur cyanide trifluoride, CF3NS, is characterized by the following bond lengths: C-N/ 116 picometers, S-C/ 174 picometers, and S-F/ 160 picometers. Using the observed bond lengths as a guide, draw a realistic lewis structure for sulfur cyanide tirfluoride and assign formal charges to each atom. Are there any resonance structures? Predict the hybridization of the C , N, and S atoms.
