备战高中：梳理选修五知识点 结构相似，在分子组成上相差一个或若干个CH2原子团的物质物质。 同系物的判断要点： 1、通式相同，但通式相同不一定是同系物。 2、组成元素种类必须相同 3、结构相似指具有相似的原子连接方式，相同的官能团类别和数目。结构相似不一定完全相同，如CH3CH2CH3和(CH3)4C，前者无支链，后者有支链仍为同系物。 4、在分子组成上必须相差一个或几个CH2原子团，但通式相同组成上相差一个或几个CH2原子团不一定是同系物，如CH3CH2Br和 CH3CH2CH2Cl都是卤代烃，且组成相差一个CH2原子团，但不是同系物。（马上点标题下蓝字"高中化学"关注可获取更多学习方法、干货！） 5、同分异构体之间不是同系物。 二、同分异构体 化合物具有相同的分子式，但具有不同结构的现象叫做同分异构现象。具有同分异构现象的化合物互称同分异构体。 1、同分异构体的种类：

⑴碳链异构：指碳原子之间连接成不同的链状或环状结构而造成的异构。如C5H12有三种同分异构体，即正戊烷、异戊烷和新戊烷。 ⑵位置异构：指官能团或取代基在在碳链上的位置不同而造成的异构。如1—丁烯与2—丁烯、1—丙醇与2—丙醇、邻二甲苯与间二甲苯及对二甲苯。 ⑶异类异构：指官能团不同而造成的异构，也叫官能团异构。如1—丁炔与1，3—丁二烯、丙烯与环丙烷、乙醇与甲醚、丙醛与丙酮、乙酸与甲酸甲酯、葡萄糖与果糖、蔗糖与麦芽糖等。 ⑷其他异构方式：如顺反异构、对映异构（也叫做镜像异构或手性异构）等，在中学阶段的信息题中屡有涉及。 各类有机物异构体情况：

高二化学选修5《有机化学基础》知识点整理 2010-2-26 一、重要的物理性质 1．有机物的溶解性 （1）难溶于水的有：各类烃、卤代烃、硝基化合物、酯、绝大多数高聚物、高级的（指分子中碳原子数目较多的，下同）醇、醛、羧酸等。 （2）易溶于水的有：低级的[一般指N(C)≤4]醇、（醚）、醛、（酮）、羧酸及盐、氨基酸及盐、单糖、二糖。（它们都能与水形成氢键）。 （3）具有特殊溶解性的： ①乙醇是一种很好的溶剂，既能溶解许多无机物，又能溶解许多有机物，所以常用乙醇 来溶解植物色素或其中的药用成分，也常用乙醇作为反应的溶剂，使参加反应的有机物和无机物均能溶解，增大接触面积，提高反应速率。例如，在油脂的皂化反应中，加入乙醇既能溶解NaOH，又能溶解油脂，让它们在均相（同一溶剂的溶液）中充分接触，加快反应速率，提高反应限度。 ②苯酚：室温下，在水中的溶解度是9.3g（属可溶），易溶于乙醇等有机溶剂，当温度高 于65℃时，能与水混溶，冷却后分层，上层为苯酚的水溶液，下层为水的苯酚溶液，振荡后形成乳浊液。苯酚易溶于碱溶液和纯碱溶液，这是因为生成了易溶性的钠盐。 ③乙酸乙酯在饱和碳酸钠溶液中更加难溶，同时饱和碳酸钠溶液还能通过反应吸收挥发 出的乙酸，溶解吸收挥发出的乙醇，便于闻到乙酸乙酯的香味。 ④有的淀粉、蛋白质可溶于水形成胶体 ．．。蛋白质在浓轻金属盐（包括铵盐）溶液中溶解度减小，会析出（即盐析，皂化反应中也有此操作）。但在稀轻金属盐（包括铵盐）溶液中，蛋白质的溶解度反而增大。 ⑤线型和部分支链型高聚物可溶于某些有机溶剂，而体型则难溶于有机溶剂。 *⑥氢氧化铜悬浊液可溶于多羟基化合物的溶液中，如甘油、葡萄糖溶液等，形成绛蓝色溶液。 2．有机物的密度 （1）小于水的密度，且与水（溶液）分层的有：各类烃、一氯代烃、氟代烃、酯（包括油脂）

高中地理选修五知识点总结

高中地理选修五知识点总结 一、我国自然灾害多发的地理背景： （一）自然背景： （1）气候背景： ①我国东部濒临太平洋，面对世界上最大的台风源区（西北太平洋台风区）。 ②位于最大的季风气候区，受强大的季风环流控制，降水时空分布极为不均。 ③气候复杂多变，气候不稳定性强。 （2）地形地质背景: ①地形复杂多样，西高东低，起伏较大，以山地丘陵为主。 ②太平洋板块俯冲，印度洋板块碰撞，地壳运动活跃。 ③处在环太平洋地震带和地中海－喜马拉雅地震带之间。 （3）生物背景： 地域辽阔，气候多样，土壤和植被类型多样，滋生和繁殖了多种有害生物。 （二）人文背景： （1）过度利用，生态环境脆弱： 我国是一个历史悠久，人口众多的农业大国，长期积累的对自然的过度利用，形成了脆弱的生态环境。人类活动对自然环境造成的破坏效应往往以各种灾害的形式表现出来。 （2）承受能力和抵御能力差： 社会经济系统对自然灾害的承受能力和防御能力低下。 （3）人口和经济密集区和灾害多发区重合： 人口和经济密度高度集中在灾害多发、易损的东部地区，这种地理分布的不平衡性在很大程度上加剧了自然灾害的严重性。 二、我国主要灾害的地域特点和形成原因： 1地震： （1）时空分布特点： 多震国家，时间上周期性，有活跃期平静期。 集中四大地区，台湾福建沿海、华北太行山沿线和京津唐地区、西南青藏高原和它边缘的四川云南两省西部、西北的新疆甘肃和宁夏。 （2）原因： 位于太平洋板块与亚欧板块的俯冲带、印度板块与亚欧板块的碰撞带，地壳运动活跃。处于环太平洋火山地震带和地中海－喜马拉雅火山地震带之间。 ②我国板块内部多断裂破碎构造。 2 滑坡、泥石流
