Question

structure of a primary alcohol and a secondary alcohol that have the molecular formula C3H8O. Write the structures of the products obtained when these alcohols are oxidised with potassium permanganate in the presence of HCl.

Answer 1

Answer:

$CH_3-CH_2-CH_2-OH\rightarrow CH_3-CH_2-COOH$

Secondary carboxylic acid

Explanation:

We are given that molecular formula $C_3H_8O$

We have to write a primary alcohol and secondary alcohol that have the given molecular formula and write the structures of the product when a primary alcohol and secondary alcohol are oxidized with potassium permanganate  in the presence of HCL.

Primary alcohol:It is that type of alcohol in which one alkyl group in the formula.

$CH_3-CH_2-CH_2-OH$

Secondary alcohol: It is that type of alcohol in which two alkyl groups in a formula of alcohol.

When a primary alcohol is oxidized with potassium permanganate in the presence of HCL the it convert into carboxylic acid because potassium permanganate is strong oxidizing agent it first convert into aldehyde and then carboxylic acid.

$CH_3-CH_2-CH_2-OH\rightarrow CH_3-CH_2-COOH$

When a secondary alcohol oxidized in presence of potassium permanganate in presence of HCl then it convert first secondary alcohol and then it convert into carboxylic acid because further oxidation due to strong oxidizing agent potassium permanganate.
