A gaseous alkane `(C_(n)H_(2n+2))` is exploded with oxygen. The volume of `O_(2)` and `CO_(2)` formed are in the ratio of 7:4, Deduce the value of n.

Text Solution

Verified by Experts

The correct Answer is:
2
`C_(n)H_(2n+2)+[n+(n+1)/(2)]O_(2)rarrnCO_(2)+(n+1)H_(2)O`
`(n+((n+1))/(2))/(n)=(7)/(4)` or n=2
