Answer to Question #93117 in General Chemistry for Nduduzo

Question

Molecular geometry of SF4, CF4, and XeF4 are;
A. The same with 1,1,1 lone pairs of electrons respectively
B. Different with 0,1,2 lone pairs of electrons respectively
C. Different with 1,0,2 lone pairs of electron respectively
D. Different with 2,0,1 lone pairs of electrons respectively

Answer 1

The answer: C. Different with 1,0,2 lone pairs of electron respectively.

Solution: The geometric structure of the molecule SF₄ is a distorted tetrahedron, since there is one lone electron pair and 4 covalent bonds.

CF₄ - tetrahedron, 4 covalent bonds and 0 unshared electron pairs.

XeF₄ - flat square, 4 covalent bonds and 2 lone electron pairs.
