WebTherefore, 2-methyl-2-butene is more stable than 2-methyl-1-butene. When a small-sized base is used for the elimination reaction, such as OH –, CH 3 O –, or EtO –, the relative stability of the product is the key factor to determining the major product. As a result, 2-methyl-2-butene is the major product for the above reaction. WebButanol is a 4-carbon, saturated, primary, aliphatic alcohol.
