A compound contains 69.5% oxygen and 30.5% nitrogen and its molecule weight is 92. The molecular formula of the compound will be -

A

`N_(2)O`

B

`NO_(2)`

C

`N_(2)O_(4)`

D

`N_(2)O_(5)`

Text Solution

Verified by Experts

The correct Answer is:
C
`"E.F is "NO_(2)`
`"E.F wt "=1xx12+2xx16=14+32=46`
`"M.wt"=92`
`"Simplest number n"=("mol.wt")/("E.F.wt")=2`
`therefore M.F=(E.F_(n)=(NO_(2))_(2)=N_(2)O_(4)`
