3. 4-Methylpent-1-ene
4. 2-Methylpent-3-one

" P " is a hydrocarbon of molecular formula:- C8H14. On ozonolysis, " P " forms "Q". "Q" on treatment with alkali under reflux condition produces "R", which on treatment with I2/NaOH gives a yellow precipitate. Acidification of the solution gives "S". The structure of "S" is given below:- [figure] The correct structure of P is
