In addition, ds-decalin has an entropy of mixing (being a racemic mixture), equal to Rln2 or 5.8 JK~'mor'. Thus the difference in entropies of the cis and trans isomers is 5.8 JKT'mor1 in favour of the cis. The experimental value is. however, ...

A common building block is decalin, which combines two cyclohexanes. There are two ways to fuse two cyclohexanes, termed cis and trans. In the trans form, the second ring is joined to the first by two equatorial connections. The trans form is ...
