∴ Generally trans is more stable then cis form. Heat of combustion (HOC) propto(1/Stability) Stability: a> b> c HOC: c> b> a

Q. The correct order of heat of combustion for following alkadienes is :

(b ) < ( c) < ( a )

(a) < (b) < (c)

(a) < (c) < (b)

(c) < (b) < (a)

$∴$ Generally trans is more stable then cis form.
Heat of combustion (HOC) $\propto \frac{1}{St abi l i t y}$
$St abi l i t y : a > b > c$
$H OC : c > b > a$

Q. The correct order of heat of combustion for following alkadienes is :

(b ) < ( c) < ( a )

(a) < (b) < (c)

(a) < (c) < (b)

(c) < (b) < (a)

∴ Generally trans is more stable then cis form. Heat of combustion (HOC) ∝Stability1​ Stability:a>b>c HOC:c>b>a

$∴$ Generally trans is more stable then cis form.
Heat of combustion (HOC) $\propto \frac{1}{St abi l i t y}$
$St abi l i t y : a > b > c$
$H OC : c > b > a$
