B.该物质的分子式为C9H15O2

C.该物质分子中含有三种官能团

D.该物质属于烃的衍生物

答案

A、分子中含有1个碳碳双键,1个醛基,能与氢气加成,所以1mol该物质能与2mol氢气发生加成反应.故A正确;

B、对于只含有C、H、O原子的分子来说,其H原子个数一定为偶数.根据结构可知该有机物分子中含有9个C原子、2个O原子、16个H原子,所以分子式为C9H16O2.故B错误;

C、分子中含有碳碳双键、醛基、羟基三种官能团,故C正确;

D、该物质是烃的含氧衍生物,故D正确.

故选B.

【探索历史的奥秘】(10分)在四川广汉三星堆出土的众多文物中,青铜器物引人注目。有论者认为,云南楚雄高峰乡彝族延续和发展了三星堆文化;他们的傩祭仪式为解读三星堆青铜器物的意义提供了某种启示。阅读下列材料:

材料一 这件青铜立人像象征当时蜀人的群巫之长,也可能就是某一代蜀王的形象。

——沈仲常《三星堆二号祭祀坑青铜主人像初记》

材料二 人们常将考古材料、文献材料、民族学的材料相结合,相对比进行研究来探索古代文化的奥秘。……从现存少数民族各种祭祀活动中看,其主持者多为巫师,也有的是长老。他们在主持祭仪时大都要穿法衣,戴法帽,手持法器,在氏族部落时期则为巫师兼酋长。高峰乡火把节傩仪主持人即(是)。……(青铜立人像)的性质确定了,其余小铜人、金面具、青铜面具便不难从高峰彝乡火把节傩仪中找到他们应有的位置,他们都是随同傩神出现的神兵神将。

——唐楚臣《广汉三星堆文化探秘》

材料三 不同学科的交互影响……产生了一系列意想不到的理论争鸣,而这些又丰富了整个的考古学讨论。

——[英]约翰逊《考古学理论导论》

请回答:

(1)据材料一、二,结合所学知识,指出青铜立人和一般小铜人的身份,并说明青铜树的象征意义。(6分)

(2)材料一、二分别属于何种学科的资料?综合上述材料,结合所学知识,指出多学科材料的综合运用对于破解三星堆历史之谜带来的积极影响。(4分)
