12*Compound X has an unknown structure, but has a molecular formula of C₂H₁2. Solve forits chemical structure. When Compound X is treated with H₂ and Pt, the only productobtained is methylcyclohexane. What alkene structures are possible candidates forCompound X?2When Compound X is treated with Br₂ and water, the product formed contains a tertiaryalcohol. Based on the first two reactions, which alkene structures are possiblecandidates for Compound X?When Compound X is treated with 03, then DMS; a single molecule results. Using allthe reaction data, what is the structure of Compound X?

Given that, the molecular formula of an unknown compound X is C7H12. We have to determine the structure of the unknown compound X. Introduction: The formula of the hydrogen defeciency index is HDI = (Number of carbon atoms + 1) - [(Number of monovalent atoms + Number of trivalent atoms)/2].The number of carbon atoms = 7, The number of monovalent atoms, H = 12. So, the HDI of the given unknown compound X is HDI = (7+1) - (12/2) = 8 - 6 = 2. That is the unknown compound X has 2 degree of unsaturation. Now, given that when compound X is treated with H2 and Pt, it produces methylcyclohexane. So, the molecule has a cyclic compound, more specifically a methylcyclohexene. Hence, the required possible structures areAlso, given that, compound X on reacting with Br2 and water gives a tertiary alcohol. So, the reaction of all the possible alkenes are shown below Hence, the required structure of compound X is 1-Methylcyclohex-1-ene. The reaction is shown belowAgain given that, the compound X on treatment with O3 and DMs give a single compound. So, this is a ozonolysis reaction, followed by reductive cleavage. The reaction is shown belowSo, the required unknown compound X is
