Chapter 4, Problem 4.60AP

Interpretation Introduction

(a)

Interpretation:

The alkene having the most stable arrangement of bonds among $\left(E\right)\text{-1, 3-pentadiene}$ and $\text{1, 4-pentadiene}$ 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.

Interpretation Introduction

(b)

Interpretation:

The heat liberated when the one mole of $\text{1, 3-pentadiene}$ is burnt is to be calculated.

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. The heat of reaction is equal to the difference between the overall heat of formation of products and the overall heat of formation of reactants respectively.
