Number of Compounds that form a clear homogenous solution with H2SO4

To determine the total number of compounds that form a clear homogeneous solution on treatment with cold dilute H2SO4, we need to analyze each compound based on its reactivity with H2SO4.

1. Propyne
- Propyne is an alkyne compound with the molecular formula C3H4.
- It is highly reactive and undergoes addition reactions with H2SO4.
- When treated with cold dilute H2SO4, propyne reacts to form a clear homogeneous solution.

2. Cyclohexanone
- Cyclohexanone is a cyclic ketone with the molecular formula C6H10O.
- Ketones are generally unreactive with dilute acids like H2SO4.
- Therefore, cyclohexanone does not undergo any significant reaction with cold dilute H2SO4 and does not form a clear homogeneous solution.

3. Cyclohexane
- Cyclohexane is a cycloalkane with the molecular formula C6H12.
- Cycloalkanes are generally unreactive with dilute acids like H2SO4.
- Therefore, cyclohexane does not undergo any significant reaction with cold dilute H2SO4 and does not form a clear homogeneous solution.

4. Propene
- Propene is an alkene compound with the molecular formula C3H6.
- Alkenes are generally reactive with dilute acids like H2SO4.
- When treated with cold dilute H2SO4, propene undergoes addition reactions and forms a clear homogeneous solution.

5. Propan-1-amine
- Propan-1-amine is an amine compound with the molecular formula C3H9N.
- Amines are generally unreactive with dilute acids like H2SO4.
- Therefore, propan-1-amine does not undergo any significant reaction with cold dilute H2SO4 and does not form a clear homogeneous solution.

6. Propoxypropane
- Propoxypropane is an ether compound with the molecular formula C6H14O.
- Ethers are generally unreactive with dilute acids like H2SO4.
- Therefore, propoxypropane does not undergo any significant reaction with cold dilute H2SO4 and does not form a clear homogeneous solution.

7. Tetrahydropyran
- Tetrahydropyran is a cyclic ether compound with the molecular formula C5H10O.
- Ethers are generally unreactive with dilute acids like H2SO4.
- Therefore, tetrahydropyran does not undergo any significant reaction with cold dilute H2SO4 and does not form a clear homogeneous solution.

8. Ethyl butanoate
- Ethyl butanoate is an ester compound with the molecular formula C6H12O2.
- Esters are generally unreactive with dilute acids like H2SO4.
- Therefore, ethyl butanoate does not undergo any significant reaction with cold dilute H2SO4 and does not form a clear homogeneous solution.

9. Pyridine
