1.	0.2 g off an organic compound contains C, H and O. On combustion, it yields 0.15 g `CO_(2) and 0.12" g "H_(2)O`. The percentage of C, H and O respectively isA. `C=15%,H=20%,O=65%`B. `C=10%,H=8.2%,O=81.8%`C. `C=12.2%,H=8.8%,O=79%`D. `C=20%,H=6.66%,O=73.34%`
Answer» Correct Answer - D % of `C=(12)/(44)xx(0.15)/(0.2)xx100=20%` % of `H=(2)/(18)xx(0.12)/(0.2)xx100=6.66%` % of `O=100-(20+6.66)=73.34%`
