How many different alkenes with molar mass 84 upon hydrogenation can g...
Understanding the problem:
To find the number of different alkenes with a molar mass of 84 that can give 3-methyl pentane upon hydrogenation, we need to consider the structural isomers of the alkene.
Identifying the key points:
1. Molar mass of alkene = 84 g/mol
2. Structure of 3-methyl pentane = CH3CH(CH3)CH2CH3
Finding the solution:
- First, we need to determine the molecular formula of the alkene that corresponds to a molar mass of 84 g/mol. Since hydrogenation adds 2 hydrogens to an alkene, the original molecular formula of the alkene would be CnH2n.
- The molecular formula of an alkene with a molar mass of 84 g/mol would be CnH2n = 84. By solving this equation, we find that n = 7.
- Therefore, the molecular formula of the alkene is C7H14.
- Now, we need to consider the structural isomers of C7H14 that can give 3-methyl pentane upon hydrogenation.
- The structural isomers that can give 3-methyl pentane upon hydrogenation are:
1. 3-methylhexene
2. 2-methylhexene
3. 3-ethylpentene
4. 2,3-dimethylbutene
5. Cyclohexene
Conclusion:
There are 5 different alkenes with a molar mass of 84 that can give 3-methyl pentane upon hydrogenation.
