Answer to Question #163610 in Organic Chemistry for fofo

Question

Calculate the molecular formulas for possible compounds with molecular masses of 136; use the Rule of Thirteen. You may assume that the only other atoms present in each molecule are carbon and hydrogen. (a) A compound with two oxygen atoms (b) A compound with two nitrogen atoms (c) A compound with two nitrogen atoms and one oxygen atom (d) A compound with five carbon atoms and four oxygen atoms

Answer 1

The molecules of these compounds are similar in size, CO2 and C3H8 both have ... Since a molecule of carbon dioxide is composed of only three atoms, its mass spectrum is very simple.
