This question is from one of my hmk assignments, i attempted it, but got confused by the different parts...
1.475g of an organic compound containing only carbon, hydrogen, oxygen and nitrogen was completely burnt in oxygen gas. The products included 2.200g of carbon dioxide and 1.125g of water. 2.360g of the compund reacted with excess alkali to produce sufficient ammonia to neutralise 18.2mL of 1.110 mol L-1 sulphuric acid. 0.177g of the vaporised compound occupied a volume of 135.8mL at 300`C and 101.8kPa.
a) Determine the empirical formula of the compound.
b) Determine the approximate molecular weight and molecular formula of the compound.
c)The compound contains a carbonyl (c=o) group. Draw a possible structural formula and give the I.U.P.A.C. name of the compound u have drawn.
i'm confused as to what happens to the N in the first part, and what the second equations (neutralization and the vaporized compound) can do to help me get the formulas. help much appreciated.
