Question

Part C: Computer Modeling 1. Sketch the Lewis structures for CH, NH, and CHF below and complete the other predicted properties. Record all data from the computer modeling below. NH VSEPR Prediction CH, Lewis structure Molecular shape Bond angle(s) Polar or nonpolar Computational Prediction Molecular shape (use wedges and dashes to sketch in 3D) Bond angle(s) Dipole moment 2. Compare the predicted bond angle for NH with the computational prediction. Explain why the bond angles differ 3. Compare the calculated dipole moments of NH, and NH,F. How are they different and why?
