Sample questions

1. Which of the following compounds is saturated?

   1. Ethane
   2. Ethene
   3. Ethyne
   4. Benzene
   Show answer

   Answer: A. Ethane

   Saturated compounds contain single bonds only. Ethane has C-C single bonds, making it saturated.

2. What type of isomerism is exhibited by butene?

   1. Structural and Geometrical
   2. Optical
   3. Conformational
   4. Functional
   Show answer

   Answer: A. Structural and Geometrical

   Butene can show both structural isomerism (position of the double bond) and geometrical isomerism (cis-trans configuration).

3. Which is the simplest ketone?

   1. Methanal
   2. Propanone
   3. Ethanone
   4. Butanone
   Show answer

   Answer: B. Propanone

   Propanone, also known as acetone, is the simplest member of the ketone family.

4. Which of the following represents an ester linkage?

   1. -COO-
   2. -NH2-
   3. -OH-
   4. -CHO-
   Show answer

   Answer: A. -COO-

   An ester linkage is characterized by the -COO- group, which forms during the condensation reaction of acids and alcohols.

5. Which reaction mechanism involves a rapid addition across a carbon-carbon double bond?

   1. Substitution
   2. Elimination
   3. Addition
   4. Rearrangement
   Show answer

   Answer: C. Addition

   Addition reactions involve breaking the double bond of alkenes and forming two new single bonds.
