Options

  1. AWhen dil. sulphuric acid reacts with aqueous solution of potassium chromate, the colour changes from yellow to orange.
  2. BWhen dil. sulphuric acid reacts with aqueous solution of potassium chromate, the colour changes from yellow to orange.
  3. CWhen dil. sulphuric acid reacts with aqueous solution of potassium chromate, the colour changes from yellow to orange.
  4. DWhen dil. sulphuric acid reacts with aqueous solution of potassium chromate, the colour changes from yellow to orange.

Correct answer

C. When dil. sulphuric acid reacts with aqueous solution of potassium chromate, the colour changes from yellow to orange.

Step-by-step solution

Ozone is a very reactive allotrope of oxygen. The reaction of ozone with alkenes and alkynes causes the oxidative cleaving of the alkene or alkyne. The carbon-carbon double bonds are replaced with carbon-oxygen double bonds, giving the required carbonyl product as shown below.

Which among the following pairs of the structures will give different products on ozonolysis? (Consider the double

In all other options both compounds will give the same product on ozonolysis.
