A) \[1:\sqrt{2}:2\]
B) 1 : 2 : 4
C) \[2:\sqrt{2}:1\]
D) \[1:2:\sqrt{2}\]
Correct Answer: A
Solution :
\[{{r}_{S{{O}_{2}}}}:{{r}_{{{O}_{2}}}}:{{r}_{C{{H}_{4}}}}=\frac{1}{\sqrt{{{M}_{S{{O}_{2}}}}}}:\frac{1}{\sqrt{{{O}_{2}}}}:\frac{1}{\sqrt{C{{H}_{4}}}}\] \[=\frac{1}{\sqrt{64:32:16}}\]\[=\frac{1}{\sqrt{4:2:1}}\] \[\frac{1}{2}:\frac{1}{\sqrt{2}}:\frac{1}{1}\]; \[\frac{2}{2}:\frac{2}{\sqrt{2}}:\frac{2}{1}\]; \[1:\sqrt{2}:2\]
