1.	10 " mL of " a gaseous organic compound containing C, H and O only was mixed with 100 " mL of " `O_(2)` and exploded under condition which allowed the `H_(2)O` formed to condense. The volume of the gas after explosion was 90 mL. On treatment with KOH solution, a further contraction of 20 mL in volume was observed. The vapour density of the compound is 23. All volume measurements were made under the same condition. Q.The volume of `CO_(2)` isA. 20 mLB. 50 mLC. 70 mLD. 90 mL
Answer» Correct Answer - A Since `H_(2)O` vapours are condensed, Volme of unreacted `O_(2)+` volume of `CO_(2)=90mL` Volume of `CO_(2)` (absorbed by KOH)`=20mL`
