高中化学竞赛知识点大全？

高中化学竞赛知识大全

　　一、物 理 性 质

　　1、有色气体：

　　F2(淡黄绿色)、Cl2(黄绿色)、Br2(g)(红棕色)、I2(g)(紫红色)、NO2(红棕色)、O3(淡蓝色)，其余均为无色气体。其它物质的颜色见会考手册的颜色表。

　　2、有刺激性气味的气体：

　　HF、HCl、HBr、HI、NH3、SO2、NO2、F2、Cl2、Br2(g);有臭鸡蛋气味的气体：H2S。

　　3、熔沸点、状态：

　　① 同族金属从上到下熔沸点减小，同族非金属从上到下熔沸点增大。

　　② 同族非金属元素的氢化物熔沸点从上到下增大，含氢键的NH3、H2O、HF反常。

　　③ 常温下呈气态的有机物：碳原子数小于等于4的烃、一氯甲烷、甲醛。

　　④ 熔沸点比较规律：原子晶体>离子晶体>分子晶体，金属晶体不一定。

　　⑤ 原子晶体熔化只破坏共价键，离子晶体熔化只破坏离子键，分子晶体熔化只破坏分子间作用力。

　　⑥ 常温下呈液态的单质有Br2、Hg;呈气态的单质有H2、O2、O3、N2、F2、Cl2;常温呈液态的无机化合物主要有H2O、H2O2、硫酸、硝酸。

　　⑦ 同类有机物一般碳原子数越大，熔沸点越高，支链越多，熔沸点越低。

　　同分异构体之间：正>异>新，邻>间>对。

　　⑧ 比较熔沸点注意常温下状态，固态>液态>气态。如：白磷>二硫化碳>干冰。

　　⑨ 易升华的物质：碘的单质、干冰，还有红磷也能升华(隔绝空气情况下)，但冷却后变成白磷，氯化铝也可;三氯化铁在100度左右即可升华。

　　⑩ 易液化的气体：NH3、Cl2 ，NH3可用作致冷剂。

知识竞赛竞赛组职责？

任何一次知识竞赛竞赛组都要预先确定好竞赛程序。竞赛程序通常分两个阶段，一是赛前准备阶段，二是竞赛实施阶段。

1、赛前准备阶段，该阶段所要进行的主要工作包括发出通知，明确竞赛试题的范围，明确参赛条件，制定竞赛规则。 2、竞赛实施阶段，主要工作有以下几次:赛前辅导;组成评委会;布置赛场;领奖工作演练;组织选手参观赛场;熟悉环境;体验抢答器和按钮;竞赛，颁奖。

(1)赛前辅导。通常在开赛前一至两天进行，辅导的内容一般包括知识和心理两个方面，知识方面的辅导主要是对题目内容进行原则性的提示，提供题目的大体范围和发问方式，心理辅导主要使选手减轻思想压力，尽快进入情况。 (2)组成评委会，评委会主要由专家释疑组的成员担任，主要对竞赛中可能出现的歧义进行纠正和解释，保证竞赛顺利进行。

(3)布置赛场，知识竞赛的现场应包括:主持台，选手台，出题板，计分显示设备，抢答器，音响设备，录相设备，电视等。

(4)竞赛与颁奖，知识竞赛的对抗性很强，因而，主持人对调节赛前气氛担负主要责任，开赛后，要严格按照规则实施，对违反竞赛规则的选手及时予以处罚，竞赛中，如果出现问题，要依靠评委会迅速解决，以保证竞赛不间断地进行，竞赛结束后，应组织好发奖。

知识竞赛的一般组织程序主要是以上内容，基层单位在进行比赛时，在程序上可有所取舍，组织上也可以简化，但无论如何，有两个环节是必须注意的:一是试题的选择与确定，二是对赛场的控制与调节
