Watson:
請問如果我想ethanal轉ethanol.可以寫NADH + H+嗎?

化學友:
Watson,雖然NADH+H+ 係可以reudce其他substance,但係考試o個時只係會o向 bio嘅respiration裡面用,考chem時係o吾接受e 隻o野o架。一般AL chem exam裡面將ethanal變成ethanol都係用下面兩個reactions:

仲有呀,用LiAlH4做reducing reagent時一定要寫(1)同埋(2),如果就咁寫"LiAlH4/ether, H2O"會冇分o架。因為如果咁樣寫係當你將LiAlH4同H2O同時撈埋一齊,LiAlH4會react with H2O immediately to give H2,LiAlH4就會失去reducing power o架啦。OK ma watson?
