Which of the following is incorrect?
Options
- ASecondary alcohols are very easily oxidised to ketones, which are oxidised to acids with same number of C-atom
- BSecondary alcohols are easily oxidised to ketones, which are oxidised to acids with lesser number of C -atoms.
- CPrimary alcohols are very easily oxidised to aldehydes, which are oxidised to acids with same number of C-atom
- DSecondary and tertiary alcohols on oxidation form acids with lesser number of C-atoms.
Correct answer
A. Secondary alcohols are very easily oxidised to ketones, which are oxidised to acids with same number of C-atom
Step-by-step solution
Primary alcohols are oxidized to aldehydes and then to carboxylic acids containing the same number of carbon atoms. This is a standard reaction sequence. Secondary alcohols are oxidized to ketones. Further oxidation of ketones involves the cleavage of carbon-carbon bonds, which results in the formation of carboxylic acids with a lesser number of carbon atoms than the original alcohol. Tertiary alcohols are resistant to oxidation under normal conditions, but under vigorous conditions, they undergo carbon-carbon bond
