Which of the following set of compounds have the same molecular formul...
The molecular formula must be the same for both the molecules but the arrangement of atoms should be different. For example, look at the structure of n-butane and isobutane. Both of these molecules have the same molecular formula that is C4H10.
Which of the following set of compounds have the same molecular formul...
Explanation:
To determine which set of compounds have the same molecular formula, we need to compare their molecular formulas.
The molecular formula of a compound indicates the number and types of atoms present in a molecule. It does not provide information about the arrangement or connectivity of atoms within the molecule.
Let's analyze each set of compounds:
a) Both (b) and (c):
- Cyclohexane: The molecular formula of cyclohexane is C6H12.
- 1-hexene: The molecular formula of 1-hexene is C6H12.
- Both compounds have the same molecular formula, C6H12.
b) Cyclohexane and 1-hexene:
- Already discussed in the previous point.
c) Butane and isobutane:
- Butane: The molecular formula of butane is C4H10.
- Isobutane: The molecular formula of isobutane is C4H10.
- Both compounds have the same molecular formula, C4H10.
d) None of these:
- This option can be eliminated since we have already identified two sets of compounds (a and c) that have the same molecular formula.
Conclusion:
The correct answer is option 'C' - Butane and isobutane. Both compounds have the same molecular formula, C4H10.
