Conjugation in OCs

Conjugation in organic compounds is important because it:

• Increases the stability of the molecule.

• alters the reactivity of molecules

• responsible for color compounds

• all of these

Which of the following is NOT a benefit of conjugation in organic compounds?

• Increased resistance to oxidation.

• Increased ability to absorb light.

• Increased melting and boiling points.

• Increased acidity.

Conjugation is important in the synthesis of organic compounds because it:

• Increases the stability of organic compounds
• Decreases the reactivity of organic compounds
• Reduces the molecular weight of organic compounds
• Enhances the color of organic compounds
