A) \[{{C}_{6}}{{H}_{10}}\]
B) \[{{C}_{7}}{{H}_{6}}{{O}_{2}}\]
C) \[{{C}_{5}}{{H}_{8}}O\]
D) \[{{C}_{9}}{{H}_{3}}O\]
Correct Answer: B
Solution :
| Element | At. wt. | Percent composition | No. of moles | Simple molar ratio |
| C | 12 | 68.5 | \[\frac{68.5}{12}=5.708\] | \[\frac{5.708}{1.67}=3.41\times 2\approx 7\] |
| H | 1 | 4.91 | \[\frac{4.91}{1}=4.91\] | \[\frac{4.91}{1.67}=2.95\times 2\approx 6\] |
| O | 16 | \[(100-68.5+4.91)\]\[=26.59\] | \[\frac{26.59}{16}=1.67\] | \[\frac{1.67}{1.67}=1\times 2\approx 2\] |
