List the side reactions/products that are formed during a dehydration of 4-methyl-2-pentanol with sulfuric acid over the course of fractional distillation, drying via potassium carbonate, and a simple distillation. This does not include the 5 alkenes (4-methyl-1-pentene, trans-4-methyl-2-pentene, cis-4-methyl-2-pentene, 2-methyl-2-pentene, and 2-methyl-1-pentene) formed.
