ethane is a molecule with 2 carbon atoms an 6 hydrogen atoms, all bonded with covalent single bonds.
ethene has the same number of carbons but 4 hydrogen atoms, the bond with carbon atoms, in this one, is a double atom
ethanoic acid reacts with ethanol in the presence of concentrated sulphuric acid as a catalyst to produce ester, ethyl ethanoate. this reaction is slow and reversible. to reduce the chances of the reverse reaction happening, the ester is distilled off as soon as it formed
soaps are water soluble-sodium or potassium salt of fatty acids. soaps are made from fats and oils, or their fatty acids by treating them chemically with a strong alkali.
