1 gm mole of an alcohol whose molecular weight is 74 contains 48 gms of carbon, 10 gms of hydrogen and 16 gms of oxygen. Its molecular formula is__________________?
Correct answer: A
Explanation
The mass ratio of C:H:O is 48:10:16. Dividing by the smallest common factor (2) gives a ratio of 24:5:8. This suggests a formula like C2H...OH.
