VSEPR, Hybridizations, aproximate values, bond angle
What hybridization would you expect for the and
atoms in urea according to the VSEPR model.
What approximate values would you expect for the various bond angles?N-C-O angle=N-C-N angle=C-N-H angle=H-N-H angleWhat are the actual hybridizations based on the molecular model shown?Could you break it down steps for me to understand how arrive to the conclusion, including clear formulas.Not just summarizing it. Would be helpful if you break it down in detain as I would like to understand it. Thanks. Make it a clearformula

Here in the structure C is in sp2 hybridization and the two N's are in sp3 hybridization.
N-C-O bond angle = 1200N-C-N bond angle = 1200C-N-H bond angle = 1070H-N-H bond angle = 1070

Why are double bonds and triple bonds shorter than single bonds?
1. Why are double bonds and triple bonds shorter than single bonds? 2. VSEPR geometry predicts that the bond angles in formaldehyde (CH20), a trigonal planar molecule, will be 120° throughout all three angles. However, analysis showed that the H-C-H bond angle is slightly smaller at 116.5°, while the two H-C-O angles are slightly larger at 121.8°. Explain this difference in the predicted bond angle vs actual bond angle. 3. VSEPR geometry also predicts that the bond angles in tetrahedral molecules is...
