AP EAMCET · Chemistry · Aldehydes and Ketones
Which of the following statement is false?
- A Only Tollen's reagent can oxidise both aliphatic and aromatic aldehydes.
- B Oximes are less acidic than hydroxylamine.
- C Sodium borohydride does not reduce carboxyl group.
- D Dialkyl cadmium is considered superior to Grignard reagent for the preparation of a ketone from an acid chloride.
Answer & Solution
Correct Answer
(B) Oximes are less acidic than hydroxylamine.
Step-by-step Solution
Detailed explanation
Oxime are more acidic than hydroxylamine because, there is a delocalisation of \(\pi\)-electrons (i.e., resonance) and it stabilises conjugate acid. While in hydroxylamine, there is no such resonance.
