The weight of carbon ,hydrogen and oxygen in an organic compound are in the ratio 6 : 1 : 8 respectively .The molecular formula of compound may be

Options

A. `CH_2O`
B. `C_3H_6O_3`
C. `CH_2O_2`
D. `C_2H_4O_4`

Answer

A, B

Explanation

The ratio of weights `{:(C ,:,H,:,O) , (6 , : ,1,:,8):}`
The atomic ratio `C : H : O`
`(6)/(12) , (1)/(1) , (8)/(16) (("weight")/("At. Weight"))`
Or `(1)/(2) : 1 : (1)/(2)`
`1 : 2 : 1`
`therefore` Empirical formula = `CH_(2)O`
`therefore` Possible molecular formulae are `CH_(2)O(A)` and `C_(3)H_(6)O_(3) (B)`
