Using bond energy data, calculate heat of formation of isoprene Given C−H, H−H, C−C, C=C and C(s)→ C(g) respectively as 98.8 kcal, 104 kcal, 83 kcal, 147 kcal, 171 kcal5C(s)+4H2(g)→H2C=C|CH3−CH=CH2-21 kcal21 kcal40 kcal50 kcal

Using bond energy data, calculate heat of formation of isoprene
Given $C - H$ , $H - H$ , $C - C$ , $C = C$ and C(s) $\to$ C(g) respectively as 98.8 kcal, 104 kcal, 83 kcal, 147 kcal, 171 kcal
$5 C (s) + 4 H_{2} (g) \to H_{2} C = C | C H_{3} - C H = C H_{2}$
