Consider the following reactants: ****** CI ******* HO-CH3 Would substitution take place at a significant rate between these reactants? Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used. If you said substitution would take place, draw all the major products in the upper drawing area below. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Oyes Ono
