What will be formed after oxidation of secondary alcohol with chromic anhydride (CrO3)?
Show Hint
- Aldehyde
- Ketone
- Carboxylic acid
- Ester
The Correct Option is B
Solution and Explanation
Step 1: When a secondary alcohol is oxidized with chromic anhydride (CrO3), it undergoes oxidation to form a ketone. Secondary alcohols do not oxidize to aldehydes or carboxylic acids.
Step 2: Thus, the correct answer is option (2).

A school is organizing a debate competition with participants as speakers and judges. $ S = \{S_1, S_2, S_3, S_4\} $ where $ S = \{S_1, S_2, S_3, S_4\} $ represents the set of speakers. The judges are represented by the set: $ J = \{J_1, J_2, J_3\} $ where $ J = \{J_1, J_2, J_3\} $ represents the set of judges. Each speaker can be assigned only one judge. Let $ R $ be a relation from set $ S $ to $ J $ defined as: $ R = \{(x, y) : \text{speaker } x \text{ is judged by judge } y, x \in S, y \in J\} $.
