Results in a decrease in the number of c-z bonds, where z is an element that is more electronegative than carbon (usually o, n, or x). results in a decrease in the number of c-h bonds. conformations are the different arrangement of atoms that are interconverted by rotation about a single bond. bonds are located in the plane of the chair conformation of cyclohexane. steric strain is an increase in energy resulting when atoms are forced too close to one another.
