Final answer:
Equatorial-equatorial repulsions are stronger than axial-equatorial repulsions.
Step-by-step explanation:
The answer to the question is a) Stronger.
Equatorial-equatorial repulsions in molecules with multiple substituents can be stronger than axial-equatorial repulsions. This is because equatorial-equatorial bonds are closer together and experience greater electron-electron repulsion compared to axial-equatorial bonds.
For example, in a molecule like cyclohexane, the equatorial-equatorial interactions between the substituents will be stronger than the axial-equatorial interactions.\
