flagpole interaction

Postby Alex 3F » Thu Mar 10, 2016 6:11 pm

In the boat conformation in cyclohexane, the intro to organic chem book says the top two hydrogens have flagpole interactions. Does flagpole interaction only describe the steric strain in the top two hydrogens in boat conformation? Or can flagpole interaction describe any hydrogens that have steric strain?

The flagpole interactions are specifically for the hydrogens or substituents that take up the two axial up positions, thus why they are flagpoles. Due to the boat conformation being this shape, it produces two axial up positions that look like flagpoles and result in steric strain.
