An organic compound having `C,H` and sulphur contains `4%` of sulphur. The minimum molecular weight of compound isA. 200B. 400C. 600D. 800 |
|
Answer» Correct Answer - D `%` of `S = ("wt. of 1 sulphur atom")/(" Minimum mol. Wt.") xx 100` `4 = (32)/(" Minimum mol.wt.") xx 100` Minimum mol. Wt =` 800 g mol^(-1)` (a) , (b) and (c ) are not possible. Alternate Method: A compound must have at leat one atom of S i.e, `32g` of S. 4g of sulphur is present in 100 g of compound. `32g` of sulphur will be present in `(100)/(4) xx 32 = 800 g mol^(-1)`. |
