Which of the following specie is not polar?
Correct answer: C. SF6
- A. PCl3
- B. SO2
- C. SF6
- D. CHCl
Explanation
SF6 (sulfur hexafluoride) is not polar. In SF6, sulfur is bonded to six fluorine atoms, and all the bond dipoles cancel each other out due to the symmetrical arrangement of the fluorine atoms around the sulfur atom. As a result, the molecule has a symmetrical geometry, and the individual bond dipoles cancel each other, resulting in a nonpolar molecule overall.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
