Question

please answer thoroughly

I. (2 pts) Consider the hybridization and bonding scheme for the compounds CH2F2, XeO3, XeF2. propylene (C3H6), and SO2. For each species: A. Draw the Lewis structures. B. Use VSEPR theory to predict the electron domain geometry about the central atom. C. Write down the hybridization for the central atom based on valence bond theory, D. Sketch the molecule showing the orbitals and any overlapping orbitals to indicate covalent bonds. E. Label all bonds using sigma or pi notation followed by the type of overlapping orbitals. (see textbook page 459 for examples) F. How many sigma and pi bonds are there in each species? G. SO2 can have two Lewis structures. Calculate the formal charges and state which is the more likely structure based on formal charge alone. Answer questions B - F for this structure only. Draw the resonance structures for both Lewis structures using a double headed arrow: + HHH H-C=C-C-H Note: The structure of propylene, C3H6, is shown here. Н

Answer 1

= 6-H - c Ç prop ene e I, U-I H- I-d Iu # H Hroz c = c-H Ino ad 3 ......... • • • when am moving from left to right carbon - 0 is surrounded by 4o bonds hence it is (sp3) hybridised has Tetrahedral Geometry. Carbon - unsaturated carbon surrounded by 3r bonds and one π bond hence it Sp² hybridi sed, hence it is a planer shape) geometry. carbon - is also surrounded by 30 bonds one π bond bence it is also sp hybridised, has planer geometry. Remem ber number of Hybrid orbitals = number of a bonds Ex! no of a bonds around a 'catom are 4 is sps, 3r is sp2, 2 Sp' one I bond u progone has so bonds
