A) \[{{C}_{2}}{{H}_{6}}\]
B) \[C{{H}_{4}}\]
C) \[{{C}_{6}}{{H}_{6}}\]
D) \[{{C}_{2}}{{H}_{3}}\]
Correct Answer: A
Solution :
For \[{{C}_{2}}{{H}_{6}},\]the total gram molecular weight =30 g Out of \[30\,g\to 26\,g\]of carbon weight, i.e., 80 per cer Same as out of \[30\,g\to 6g\,{{H}_{2}}\] weight, i.e., 20 per cent. Hence, the correct option is (a).
