An alcohol is converted to an aldehyde with same number of carbon aroms as that of alcohol in the presence of K2Cr2O7/H2SO4 alcohol is:
Correct answer: B. CH3CH2CH2OH
- A. CH3C(CH3)2OH
- B. CH3CH2CH2OH
- C. (CH3)3COH
- D. (CH3)2CHOH
Explanation
Primary alcohols produce aldehydes upon oxidation.When CH3CH2CH2OH, which is 1-propanol, is treated with K2Cr2O7/H2SO4, it undergoes oxidation and gets converted into an aldehyde. The resulting aldehyde will have the same number of carbon atoms as the original alcohol, so in this case, it would be propanal (CH3CH2CHO). The K2Cr2O7/H2SO4 acts as an oxidizing agent, helping in the conversion of the alcohol group to the aldehyde group.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
