Condensation involves which of the following reactions?
Correct answer: A. Elimination + addition
- A. Elimination + addition
- B. Elimination + substitution
- C. Addition + substitution
- D. None of these
Explanation
Option A is correct since condensation reactions involve the elimination of small molecules in the form of water or HCl. Then the other molecules are simply joined to the first molecules resulting in the addition of the other molecule.Option B is incorrect since it mentions that elimination occurs in condensation but substitution does not occur in condensation. It is the simple linking together of two molecules, no replacement occurs.Option C is incorrect since it does mention addition but substitution is not correct.Option D is incorrect since it mentions none of these, which is not the case.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
