A) \[{{C}_{4}}{{H}_{8}}{{O}_{4}}\]
B) \[{{C}_{6}}{{H}_{12}}{{O}_{6}}\]
C) \[{{C}_{3}}{{H}_{6}}{{O}_{3}}\]
D) \[{{C}_{5}}{{H}_{10}}{{O}_{5}}\]
Correct Answer: B
Solution :
The molecular formula = Empirical formula \[\times \]Number of atoms. Number of atoms \[\text{=}\frac{\text{Molecular}\,\text{wight}}{\text{Emprical}\,\text{formula}\,\text{weight}}=\frac{180}{30}=6\] (Here empirical formula\[C{{H}_{2}}O,\,weight=12+2+16=30\]) So, molecular formula \[=C{{H}_{2}}O\times 6={{C}_{6}}{{H}_{12}}{{O}_{6}}\] Hence, the correct option is (b).
