In the boat conformation the two bonds shown in red (2) are called flagpole bonds. The hydrogen atoms on the flagpole bonds are called flagpole hydrogens. Close proximity of the flagpole hydrogens results in steric strain. Eclipsing of carbon-hydrogen bonds on adjacent carbon atoms (3) results in torsional strain.
