Question

13) Draw Lewis structures of the following molecules to show their bonds and lone pairs. Then answer the following questions about them. Include all the valence electrons in your drawings. H2O IF 3 CO2 How many valence electrons does each molecule have? How many core electrons does each molecule have? How many bonding electrons does each molecule have? How many lone pairs does each entire molecule have? What is it's electrónic geometry? What is it's molecular geometry? What is the hybridization of the central atom?

Answer 1

H₂O H-OH O 13² 25² 2p4 Valence election = 6 Core election = 2 Bond=2 - Bonding election = 2x2 =4 Number of love pair = 2 Molecular geometry Bent Electronic geometry Tetrahedral Hybridization & Spª 7: If H - - I zobap berbagai [kr] Yd 055² sps Valence election = 7 (ss² sps). care electron = 18 (45², ups, id) Bonding election = 2x3=6 Number of lone pair = 2+3(31= 11 Molecular geometry T shaped Electronie geometry Trigonal Pyronidal Hybridization → Sp²d²

o=c=8 → 15² 252 2p² V Valence dectron care elections Bonding dection = Ubond X2 a 442=8. Number of lone pair a 4 Electronie geometry Molecular geometry Hybridization - → Linear Linear Sp
