Question

Date Laboratory Exercises Using a molecular modeling kit, construct models of each of the compounds in the tables below. Complete the following three tables by first drawing a simple sketch of the molecule showing which atoms are attached to each other, the number of bonds between each pair of atoms, and any nonbonding electrons. Then, draw the molecule again showing the actual shape and the angles between the atoms as accurately as you can. The first one has been completed as an example. CHEMICAL FORMULA SIMPLE SKETCH OF MOLECULE SKETCH INCLUDING BOND ANGLES H all angles 109.5 CH4 CH Cl20 NCI3 CH20

Answer 1

Chemical formula: implies cl_2 O simple sketch of molecule: implies SKETCH INCLUDING BOUND ANGLE: implies angle Cl - O - Cl = 111 degree chemical formula: implies NCl_3 simple sketch: implies sketch including bound angle: implies angle Cl - N - cl = 108 degree \r\n chemical formula: impliesCH_2 O simple sketch of molecule: implies sketch including bound angle: implies angle H - C - H = 115 degree angle H - C = 0 122 degree questions 1 Explain why the CO_2 molecule is linear instead bent implies In CO_2 molecule, the no. of e^minus circle in the valance e^minus circle of C atom + 4 electron of two double bounded '0'atoms = 8 electrons = 4 electron pairs = 25 bounded pair (r - bp) + 2 pi bounded pair (pi - bp) \r\n Now, the pi - bp have no role in the determination of the shape of the molecule So the two r - bp will determine the shape of the molecule
