Options:
A) $ C _2H _2 $
B) $ CO $
C) $ O _2 $
D) $ CH _4 $
Show Answer
Answer:
Correct Answer: A
Solution:
$ \because $ 1L of gas at S.T.P. weight 1.16g
$ \therefore $ 22.4 L of gas at S.T.P. weight $ =22.4\times 1.16 $ $ =25.984\approx 26 $ This molecular weight indicates that given compound is $ C _2H _2 $ .
