When two six-membered rings share a C–C bond, this bicyclic system is called a decalin. There are two possible arrangements: trans-decalin having two hydrogen atoms at the ring fusion on opposite sides of the rings, and cis-decalin having the two hydrogens at the ring fusion on the same side.a. Draw trans- and cis-decalin using the chair form for the cyclohexane rings.b. The trans isomer is more stable. Explain why.
