Question

Experiment 13 Advance Study Assignment: The Geometrical Structure of Molecules You are asked by your instructor to construct a model of the CH,CI molecule. Being of a conservative nature, you proceed as directed in the section on Experimental Procedure First you need to find the number of valence electrons in CH,CI. The number of valence electrons in an atom of an element is equal to the last digit in the group number of that element in the Periodic Table. 1. Cl is in Group C is in Group H is in Group In CH,CI there is a total of The model consists of balls and sticks. What kind of ball should you select for the C atom? are paired, and each stick represents an electron pair. How many sticks do you need? Assemble a skeleton structure for the molecule, connecting the balls with sticks into one unit. Use the below: valence electrons 2· the H atoms?the Cl atom? The electrons in the molecule 3. C atoms form four bonds, whereas Cl atoms usually do not. Draw a sketch of the skeleton 4. How many sticks did you need to make the skeleton structure? How many sticks are left If your model is to obey the octet rule each ball must have four sticks in it (except over? for hydrogen atom balls, which need only one). (Each atom in an octet rule species is surrounded by four pairs of electrons.) How many holes remain to be filled? sticks, which represent nonbonding electron pairs. Draw the complete Lewis structure for CH3CI using lines for bonds and pairs of dots for nonbonding electrons. Fill them with the remaining Describe the geometry of the model, which is that of CHCl· polar?Why? 5. Is the CHCl molecule Would you expect CH,CI to have any isomeric forms? Explain your reasoning. 6. Would CH,CI have any resonance structures? If so, draw them below

Explanation / Answer

1.

C has 4 valence electrons therefore present in group no 4

H has 1 valence electron therefore present in group no 1

Cl has 7 valence electron but 17group has last digit no 7 thus Cl present in group no 17.

since carbon has 4 valence electrons,each hydrogen has 1 valence electron and Cl has 7 valence electrons therefore total valence electrons is 14
