複選題48. 目前，大部分的汽車是使用汽油為動力，讓汽油蒸氣在汽缸內燃燒（活塞將汽油與空氣 混合壓縮後，火星塞再點火燃燒）。倘燃燒太急速時，便會發生引擎不正常燃爆現象， 稱為爆震（震爆）。目前國內使用的汽油為 92，95，98 等級之無鉛汽油；有鉛汽油是指 在汽油中加入屬於有機鉛的化合物，但會導致車輛排氣中混有鉛微粒或鉛化物。研究顯 示，都市地區空氣中含鉛之 90%來自汽車含鉛的廢氣，鉛會累積在人體內影響血管、心 臟、內分泌及免疫系統；此外，鉛具慢毒性，兒童更易由空氣中吸入鉛成分，致使腦部 受損。有關汽油的敘述，下列那些正確? (A) 汽油的主要成分是 C4~C12 之脂肪烴和環烴類混合物 (B) 汽油中添加有機鉛或酒精可改善汽車的爆震 (C) 汽油中所添加的有機鉛為四乙基鉛 (C2H5)4Pb，除了可改善汽車的爆震外，亦可增加 汽油的辛烷值 (D) 含鉛汽油燃燒時會產生固體一氧化鉛和鉛 (E) 近幾年來，部分國家地區已開始使用 Fe(CO)5 等代替四乙基鉛 (C2H5)4Pb 作爲汽油抗 震劑
