Draw the 2 chair conformations of cis-1,3 dimethylcyclohexane. Ina stable. Cyclohexane. Indicate which is the most 9. Which energy diagram below indicates a 1 step reaction that is exothermic?

Answer 1

& As the branching increases boiling point decrease. So and compound has les boiling powt cis 1, 3 dimethyl cydo hexane CHE A is more stable than B because in a where both methyl group are in axial position there will be 1,3-dioxial interaction For exothermic readon, enugy is released so products have lower enugy than reactants so cnagy diagram for owthermic reaction is a @ Reaction progress en secondary ① Tatiany Carbocalon 2 crore stable CHE C-CHD C b) CH₂-CH ₂ -C- CH3 Alan ch₂ -CH -c=ch
