AP EAMCET · Chemistry · Aldehydes and Ketones
Choose the incorrect statement among the following.
A. The reactivity of aromatic aldehydes and ketones is less than that of aliphatic carbonyl compounds towards nucleophilic addition reactions.
B. Benzaldehyde does not give Fehling's test.
C. The \(\mathrm{H}\)-atoms in ethanal are acidic in nature.
D. \(p\)-nitro benzaldehyde is less reactive than benzaldehyde towards nucleophilic addition reactions.
- A A
- B B
- C \(\mathrm{C}\)
- D D
Answer & Solution
Correct Answer
(D) D
Step-by-step Solution
Detailed explanation
(A) Because of the attachments of bulkier groups (aryl), the attack of nucleophile to the \(s p^2\) carbon of \( > \mathrm{C}=\mathrm{O}\) group will face steric repulsion. So, rate of the reaction will decrease. (B) Fehling's solution is being a very mild oxidising agent,…
