世界卫生组织疾病传染部主任纳瑞恩曾在新加坡举办的第三届禽流感高峰会上警告，全球可能爆发大规模禽流感疫情，导致约700万人死亡。莽草酸是一种合成治疗禽流感药物达菲的原料，鞣酸存在于苹果、生石榴等植物中。下列关于这两种有机化合物的说法正确的是（ ）
A．两种酸都能与溴水发生取代反应
B．两种酸遇三氯化铁溶液都显色
C．鞣酸分子与莽草酸分子相比多了两个碳碳双键
D．等物质的量的两种酸与足量金属钠反应产生氢气的量相同
答案：D
莽草酸中不含苯环只含碳碳双键，只能和溴水发生加成反应，鞣酸中含酚羟基能和溴水发生取代反应，A项错；莽草酸中无苯环，不能与三氯化铁溶液发生显色反应，B项错；鞣酸中有苯环无碳碳双键，C项错；1 mol的两种酸中均含4 mol羟基，均与4 mol Na反应生成4 g氢气，D项正确。
