To determine the correct formula for chloroform, we need to understand the composition and structure of the molecule.
Chloroform is an organic compound that consists of carbon (C), hydrogen (H), and chlorine (Cl) atoms. The molecular formula for chloroform is CHCl3.
From the options provided:
A) CHCl5 - This formula has an extra chlorine atom compared to the correct formula for chloroform.
B) CH2Cl2 - This formula represents dichloromethane, which is a different compound with a different structure.
C) CHCl3 - This is the correct formula for chloroform.
D) CCl4 - This formula represents carbon tetrachloride, which is a different compound with a different structure.
Therefore, the correct answer is C) CHCl3.
