A hydrocarbon with molecular formula C6H8 is chiral but upon catalytic...
Introduction:
The question asks us to identify the hydrocarbon with the molecular formula C6H8 that is chiral but becomes achiral upon catalytic hydrogenation, resulting in a hydrocarbon with a molar mass of 86 g/mol.
Explanation:
To determine the correct answer, let's analyze each option and eliminate the incorrect ones.
Option A: 5-methyl-1,3-cyclopentadiene
- The molecular formula is C6H8, which matches the given information.
- However, this compound does not contain any double bonds, which means it cannot undergo catalytic hydrogenation to become achiral.
- Therefore, option A is incorrect.
Option B: 1,4-dimethylcyclobutadiene
- The molecular formula is C6H8, which matches the given information.
- This compound contains two double bonds, which can undergo catalytic hydrogenation to become achiral.
- However, upon catalytic hydrogenation, the molar mass of this compound would increase, as hydrogen atoms would be added to the double bonds.
- Therefore, option B is incorrect.
Option C: 1-ethenyl-3-methylcyclopropene
- The molecular formula is C6H8, which matches the given information.
- This compound contains one double bond, which can undergo catalytic hydrogenation to become achiral.
- However, upon catalytic hydrogenation, the molar mass of this compound would increase, as hydrogen atoms would be added to the double bond.
- Therefore, option C is incorrect.
Option D: 3-methyl-1-pentene-4-yne
- The molecular formula is C6H8, which matches the given information.
- This compound contains one double bond and one triple bond. Upon catalytic hydrogenation, both the double bond and triple bond would be converted to single bonds, resulting in an achiral compound.
- The molar mass of this compound is 86 g/mol, which matches the given information.
- Therefore, option D is the correct answer.
Conclusion:
Among the given options, the hydrocarbon with the molecular formula C6H8 that is chiral but becomes achiral upon catalytic hydrogenation, resulting in a molar mass of 86 g/mol, is option D: 3-methyl-1-pentene-4-yne.
