The masses of carbon, hydrogen and oxygen in ann organic compound are in the ratio 6:1:8 respectively. Which of the following pairs of formulae correspond to above information?A. `CH_(3)O and CH_(3)CHO`B. `CH_(2)O and C_(3)H_(6)O`C. `C_(3)H_(6)O and C_(2)H_(6)O_(2)`D. `C_(3)H_(6)O_(3) and HCHO`

Answer» Correct Answer - D
In `C_(3)H_(6)O`, mass of 3C-atoms`=12xx3=36` mass of 6 H-atoms `=1xx6=6`
mass of 3 O-atoms`=16xx3=48`
`therefore`Ration of masses of `C:H:O` is 36:6:48 or 6:1:8, In HCHO, mass of 1C-atom=12
mass of 2 H-atoms=2
mass of 1 O-atom=16
`therefore`Ratio of masses of `C:H:O` is 12:2:16 orr 6:1:8
