Question 1

What are polar covalent bonds?

Answer 1

• Unsymmetrical bonds
• Difference in E.N.
• contain dipoles

Question 2

What are nonsymmetrical compounds considered?

Answer 2

Nonsymmetrical compounds are considered polar.

Question 3

What are symmetrical compounds considered?

Answer 3

Symmetrical compounds are considered nonpolar.

Question 4

What is the inductive effect?

Answer 4

The inductive effect is induced polarity in a molecule or the shifting of an electron in a bond in response to electronegativity of nearby atoms

Question 5

True or False: Something that has the inductive effect is a lot more stable than something that does not have inductive effect.

Answer 5

This is true. Something that has the inductive effect is a lot more stable than something that does not have it.

Question 6

If a molecule has inductive effect does that mean it is polar or nonpolar?

Answer 6

If a molecule has an inductive effect then the molecule is polar.

Question 7

True or False: Nonpolar molecules are more stable than polar molecules.

Answer 7

This is false. Polar molecules are more stable than nonpolar molecules.

Question 8

True or False: Nonpolar compounds have lower boiling and melting point than polar compounds.

Answer 8

This is True. Polar compounds have a high boiling and melting point than nonpolar compounds.
