Facts about the test: The AP Chemistry exam has 60 multiple choice questions and you will be given 1 hour 30 minutes to complete the section. That means it should take you around 15 minutes to complete 10 questions.

A. The molecular geometry for both substances is different because S has a greater number of electron domains than C.

B. Both molecules have the same shape because the molecular formulas are the same.

C. Both molecules have similar shapes and are nonpolar because the electronegativities for C and S are similar.
