Assertion :When one mole of $C_{3} H_{6}$ is subjected to combustion, 3 moles of $C O_{2}$ and 3 moles of $H_{2} O$ are formed. Reason: Combustion of any hydrocarbon produces equal number of moles of $C O_{2}$ and $H_{2} O$ .

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is C Assertion is correct but Reason is incorrect
Balance Chemical equation is
$2 C_{3} H_{6}$ + $9 O_{2}$ $\to$ $6 C O_{2}$ + $6 H_{2} O$
so,
on doing mole mole analysis we find that When one mole of
$C_{3} H_{6}$ is subjected to combustion, 3 moles of $C O_{2}$ and 3 moles of $H_{2} O$ are formed.

from above balance chemical equation we conclude that Assertion is correct but Reason is incorrect
hence option C is correct.
