16.46 Rank the following compounds in order of increasing reactivity in electrophilic bromination. In each case, indi- cate whether the principal monobromination products will be the ortho and para isomers or the meta isomer, and whether the compound will be more or less reactive than benzene. Explain carefully the points that cause any uncertainty. N(CH3)3 deact CH,N(CH3)3 A meta N(CH,)2 -CH3 act act
