The compound 2-bromobutane, CH3CHBrCH2CH3 , can react with sodium hydroxide to form compounds M, N and O. Compound M, C4H10O, exists as a pair of optically active isomers. Compounds N and O, C4H8, are structural isomers, and compound O exists as a pair of geometrical isomers. Write equations, using curly arrows to represent the movement of electron pairs, to show the mechanism of the reaction in which N is formed. Which compound is a member of the same homologous series as 1-chloropropane? Which formula is a correct representation of pentane? What is the organic product of the reaction between ethanol and ethanoic acid? Explain why the incomplete combustion of hydrocarbons is harmful to humans.
