1.	`0.5g` of hydrocarbone gave `0.9 g ` water on combustion . The percentage of carbon in hydrocarbon isA. `75.8`B. `80.0`C. `56.6`D. `28.6`
Answer» Correct Answer - b `%` of `H=(2)/(18)xx(wt. of H_(2)O)/("wt. of organic compound" )xx100` `=(2)/(18)xx(0.9)/(0.5)xx100=20%` Since percentage of hydrogen is 20. Therefore , remaining is carbon `i.e., 80%`
