aw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant
rate under these conditions, check the box underneath the drawing area instead.
Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products.
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.
