What is the molecular formula of chloroform? A. CCl4 B. CHCl3 C. CH4 D. C2H6

CCl4
CHCl3
CH4
C2H6

The correct answer is $\boxed{\text{B. CHCl3}}$.

Chloroform is a chemical compound with the formula $\ce{CHCl3}$. It is a colorless, dense, and highly flammable liquid that is used as a solvent and anesthetic. It is a trichloromethane, and is a member of the haloalkane family.

The other options are incorrect because they do not have the correct molecular formula for chloroform. Option A, $\ce{CCl4}$, is the molecular formula for carbon tetrachloride. Option C, $\ce{CH4}$, is the molecular formula for methane. Option D, $\ce{C2H6}$, is the molecular formula for ethane.
