Answer to Question #277323 in General Chemistry for Chan

Question

Using Valence shell Electron Pair Repulson (VSEPR) theory, predict the molecular geometry of Carbon tetrachloride, CCl4

Answer 1

The Lewis structure shows that there are four electron regions about the central carbon atom.

The VSEPR model states that the electron regions around an atom spread out to make each region is as far from the others as possible. For these clouds in CCl4 to be as far as possible from one another, they will point toward the corners of a tetrahedron.

The bonds will emanate from the central atom at angles of 109.5 ° to each other.

The structure will be tetrahedral.
