Concept introduction:
The free energy diagram of a reaction is the plot of standard free energy versus reaction coordinate or reaction progress. The products and reactants are placed at their respective free energy. The difference in the free energy of products and reactants is the standard free energy of the reaction.
Similarly, the energy diagram is also drawn using the heat of formation of compounds.
(b)
Interpretation:
The ranking of alkenes in decreasing order of their stability is to be stated.
Concept introduction:
The heat of formation of a compound is linked to its stability. The lesser is the heat of formation of compound more stable is the compound and vice-versa. The heat of formation is widely used to explain the stability of alkenes having a different structural formula.
(c)
Interpretation:
The energy difference between the heat of formation of alkenes is to be stated with explanation.
Concept introduction:
The heat of formation of a compound is linked to its stability. The lesser is the heat of formation of compound more stable is the compound and vice-versa. The heat of formation is widely used to explain the stability of alkenes having a different structural formula.
(d)
Interpretation:
An explanation for the stability order of the alkenes is to be stated.
Concept introduction:
The stability of the structural isomers of alkenes is one of the important topics. The stability of alkenes is explained on the basis of hyperconjugation and resonance factor. The alkene having the most number of hyperconjugation structures is more stable.

- 1,4-Pentadiene (CH2=CH-CH2-CH=CH2) is a liquid at room temperature and has a density of 0.66 g/mL and molar mass of 68.12 g/mol. In a laboratory experiment, 3.80 mL of this compound was treated with 4.80 mL of conc. H2SO4 (100% w/w; molar mass 98.08 g/mol). Note that the density of conc. H2SO4 is 1.84 g/mL. The resulting sulfate ester was then treated with 1.20 mL of water (molar mass 18.02 g/mol) affording, after work- up, 2,4-pentanediol (molar mass 104.15 g/mol) as the crude product. The crude product was then purified by simple distillation, which yielded 2.00 g of pure product. a.
