Nine volumes of gaseous mixture consisting of gaseous organic compound A and just sufficient amount of oxygen required for complete combustion yielded on burning 4 volumes of `CO_(2)`, 6 volumes of water vapours, and 2 volumes of `N_(2)`, at all volumes measured at the same temperature and pressure. If the compounds contains `C, H`, and `N` only, the molecular formula of compound `A` is

A

`C_(2)H_(3)N_(2)`

B

`C_(2)H_(6)N_(2)`

C

`C_(3)H_(6)N_(2)`

D

`C_(3)H_(6)N`

Text Solution

Verified by Experts

The correct Answer is:
B
`underset({:(2x = 4),(2y = 12),(2z = 4):})(2C_(x))H_(y)N_(z) + 7 O_(2) rarr underset({:(x = 2),(y = 6),(z = 2):})(4CO_(2)) + 6H_(2) O + 2N_(2)`
Formula `= C_(2)H_(6)N_(2)`
