The correct order of heat and combustion for the following alkadienes is
Options
- A(ii) < (iii) < (i)
- B(i) < (ii) < (ii)
- C(iii) < (ii) < (i)
- D(i) < (iii) < (ii)
Correct answer
B. (i) < (ii) < (ii)
Step-by-step solution
ΔH comb .   ∝   1 Stability   of   alkadiene Stability → (i) > (ii) > (iii) Δ H c o m b . → (i) < (ii) < (iii)
