The energy cost associated with the eclipsing interaction between a bromine atom and a hydrogen atom in bromoethane is needed to be calculated on basis of given information the barrier to rotation of bromoethane is 15 kJ/mol. Concept introduction: Conformations are arising due to the free rotation of C − C bond. These rotations are measured by dihedral angle ; it is the angle between two atoms attached to two different carbons of C − C rotation in Newman projection. The most and least energy occupied conformers are eclipsed and staggered , which are having a dihedral angle of ‘0’ and ‘60’ degree respectively. The torsional strain and steric interaction between atoms of eclipsed conformations makes them more energized as compared to staggered conformations. The C − C bond rotation from staggered to eclipsed is called barrier to rotation. It requires some cost of energy . It depends upon eclipsed interaction energies of each atom attached to C − C carbon atom. The energy cost for H/H eclipsed interaction is 4 kJ/mol. To find: the energy cost associated with the eclipsing interaction between a bromine atom and a hydrogen atom in bromoethane.
