Write the structural formulae for : 1,3-dimethylcyclohexane

Answer

`ArarrS; BrarrR; CrarrP; DrarrQ`

Explanation

Process AC = polytropic process (P = KV)
Molar Heat capacity `c_(m)=c_(v)+R//2=2R`
Process AB = Isobaric
`c_(m)=c_(p)=5R//2`
`(q_(AC))/(q_(AB))=(underset(T_(A))overset(T_(C))intnC_(m).dT)/(underset(T_(A))overset(T_(B))intn.C_(p,m).dT)=(2R)/((5)/(2)R)=0.8`:
`(q_(AC))/(q_(AB))xx10=0.8 xx10=8`
