MOLECULAR POLARITYFIELD NOTE 86 / 175

Is CHCl3 polar or nonpolar?

CHCl3 is polar because three C–Cl bonds and one C–H bond do not cancel in its tetrahedral arrangement.

THE ANSWERPolar.

Chloroform · tetrahedral

THE REASONING

Why CHCl3 is polar

Chloroform has three chlorine atoms and one hydrogen arranged tetrahedrally around carbon. The three C–Cl dipoles all point in a similar direction (toward Cl), and while the single C–H dipole partially opposes them, it is insufficient to cancel them.

A USEFUL DISTINCTION

What to notice

Three chlorines and one hydrogen do not occupy equivalent roles around carbon. The tetrahedral arrangement therefore retains a net dipole.

Common questions about CHCl3

  1. 01
    What does the Lewis structure of CHCl3 show?

    C makes three C–Cl single bonds and one C–H single bond. Each Cl has three lone pairs.

  2. 02
    What is the molecular geometry of CHCl3?

    CHCl3 has a tetrahedral molecular geometry. The 3D model shows representative bond angles of 110.6° and 108.3°. These angles come from the displayed model coordinates.

  3. 03
    What is the molar mass of CHCl3?

    CHCl3 has an approximate molar mass of 119.37 g/mol, calculated from its formula using abridged standard atomic weights. Natural isotope variation can change the last digits.
