Write a mechanism using sodium ethoxide in ethanol for the epimerization of cis-decalone to trans-decalone. Draw chair

Question:

Write a mechanism using sodium ethoxide in ethanol for the epimerization of cis-decalone to trans-decalone. Draw chair conformational structures that show why trans-decalone is more stable than cis-decalone. You may find it helpful to also examine handheld molecular models of cis- and trans-decalone.
