Indicate which of the following substances contain an atom that does or does not follow the octet rule.

A. AlCl3

B. PCl3

C. PCl5

D. SiCl4

Explain why trans-1,2-difluoroethane is a non-polar molecule that while cis-1,2-difluoroethane is a polar molecule.

Acrylonittrile has the formula CH2=CH-CN. Draw a line bond formla for acrylonitrile and label sigma bonds, pi bonds, which carbon atoms are sp2 hybridized and which carbon are sp hybridized.
