Molecular Geometry and Polarity of CCl4

The video tutorial explains how to determine if CCl4 is polar or nonpolar by examining its Lewis structure and molecular shape. The symmetrical arrangement of chlorine atoms around the central carbon atom leads to a uniform electron distribution, resulting in no net dipole moment. Consequently, CCl4 is identified as a nonpolar molecule.

What is the primary purpose of using Lewis structures in chemistry?

• To calculate the boiling point

• To find the molecular weight

• To determine the color of a molecule

• To understand electron distribution

How do chlorine atoms in CCl4 arrange themselves?

• In a linear fashion

• As close as possible to each other

• Spread out as far as possible

• In a circular pattern

What shape does the CCl4 molecule form due to the arrangement of chlorine atoms?

• Tetrahedral

• Linear

• Bent

• Trigonal planar

What does the molecular surface of CCl4 indicate about its charge distribution?

• It has a net negative charge

• It has alternating positive and negative charges

• It has a net positive charge

• The charge is uniformly distributed

Why is CCl4 considered a nonpolar molecule?

• Because it has a high boiling point

• Due to the cancellation of dipoles

• Due to its ionic bonds

• Because it is a gas at room temperature

What is the net dipole moment of CCl4?

• Zero

• Undefined

• Negative

• Positive

Which element in CCl4 has a higher electronegativity?

• Neither has electronegativity

• Both have the same electronegativity

• Chlorine

• Carbon

What is the significance of the symmetrical arrangement of chlorine atoms in CCl4?

• It makes the molecule polar

• It causes the molecule to be unstable

• It leads to a net dipole moment

• It results in a nonpolar molecule
