Problem: Predict the relative bond angles in CCl4 and H2O .a. CCl4 bond angles > H2O bond angleb. H2O bond angle > CCl4 bond anglesc. CCl4 bond angles = H2O bond angled. Relative bond angles cannot be predicted.

FREE Expert Solution

 Since we don’t know the Lewis structure for H2O and CCl4, we need to do the following steps:


Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Determine the number of electron groups around the indicated atom.

Step 5: Determine the electron geometry and bond angle using this:


Electron Regions          Electronic Geometry          Bond Angles

2                                      linear                                    180˚

3                                      trigonal planar                      120˚

4                                      tetrahedral                            109.5˚

5                                      trigonal bipyramidal              90˚, 120˚, and 180˚

6                                      octahedral                            90˚ and 180˚
