1. 你之前有題mechanism 有無答案?是不是HONO2 的OH的O打落去H2SO4個H到,甩左水,因為H2SO4係more acidic than HONO2跟住NO2+再比double bond of benzene attack,跟住就照做落去..
2. 我想問下..atom economy如果有隻reactant 係in excess,咁係計formula mass of reactant定係mass of reactant?thx.

1. hahayi2007,其實o個mechanism寫到下面咁就滿分o架啦:

2. 任何時間都係用formula mass of reactants o黎計o架。
