Question

Benzene when heated in air burns with ________ and produces $C{O}_2$ and $H_{2}O$.

• A. sooty flame
• B. non-sooty flame
• C. light color flame
• D. none of these

Answer 1

The correct option is A sooty flame

Benzene when heated in air burns with a sooty flame and produces $C{O}_2$ and $H_{2}O$.
$C_6{H}_6+\frac{15}{2}{O}_2\to 6C{O}_2+3H_{2}O$

Note: Incomplete combustion of unsaturated hydrocarbons give sooty flame due to the presence of black unburnt carbon particles.
