Default 手机监听器/手机窃听器/手机卡监听器 │分子晶体

冰(H2O)分子晶体棍球模型
干冰

定义  分子间通过火子间作用力(包含范德华力和氢键)形成的晶体。典范的分子晶体  ①所有 非金属氢化物   ②大部门非金属单质,如:罕见气体、卤素(X2)、氧气、硫(S8)、氮(N2)、白磷(P4)、C6 0等   ③局部非金属氧化物,如:CO2、SO2、SO3、P4O6、P4O10等   ④简直所有的酸   ⑤绝大多数有机化合物,如:苯、乙酸、乙醇、葡萄糖等   ⑥所有常温下呈气态的物质、常温下呈液态的物质(除汞外)、易挥发的固态物质性质  分子晶体是由分子 组成,护航新消费・315消费者网购维权专题,能够是极性分子,也可以长短极性分子。分子间的作用力很弱,分子晶体存在较低的熔、沸点,手机监听器/手机窃听器/手机卡监听器,硬度小、易挥发,窃听器哪里买 │122中型坦克,很多物质在常温下呈气态或液态,例如O2、CO2是气体,乙醇、冰醋酸是液体,手机监听器/手机窃听器/手机卡监听器。同类型分子的晶体,其熔、沸点随分子量的增长而升高,例如卤素单质的熔、沸点按F2、Cl2、Br2、I 2次序递增;非金属元素的氢化物,按周期系同主族由上而下熔沸点升高;有机物的同系物随碳原子数的增添,熔 沸点升高。但HF、H2O、NH3、CH3CH2OH等分子间,除存在范德华力外,还有氢键的作使劲,它们 的熔沸点较高,寿庄固伦公主。在固态和熔融状况时都不导电,窃听器哪里买 │六旬翁自制水上自行车 资料多是成品能承重千斤。   分子组成的物资,行中书省,其溶解性遵照“相似相溶[1]”原理,极性分子易溶于极性溶剂,非极性分子易溶于非极性的有机溶剂,例如 NH3、HCl极易溶于水,难溶于CCl4和苯,手机监听器/手机窃听器/手机卡监听器;而Br2、I2难溶于水,窃听器哪里买 │腊八蒜,易溶于CCl4、苯等有机溶剂。依据此性质,手机监听器/手机窃听器/手机卡监听器,可用CCl4、苯等溶剂将Br2跟I2从它们的水溶液中萃取、分别出来,赶集,手机监听器/手机窃听器/手机卡监听器。分子晶体熔沸点高下规律  分子间作用力越强,熔沸点越高   ①组成和结构相似的分子晶体,普通绝对分子品质越大,手机监听器/手机窃听器/手机卡监听器,分子间作用力越强,熔沸点越高。例如:元素周期表中第ⅦA族的元素单质其熔沸点变更法则为: At2>I2 > Br2 > Cl2>F2 。    ②若分子间有氢键,则分子间作用力比结构相似的同类晶体大,故熔沸点较高。例如:HF > HI > HBr > HCl,手机监听器手机窃听器手机卡监听器监听器材 │中国特点军事变更。   H2O> H2Se> H2S,邪神传说。 NH3> PH3   ③组成和构造不相似的物质,分子极性越大,其熔沸点越高,例如:CO>N2   ④在有机物的同分异构体中,个别来说,支链越多,手机监听器/手机窃听器/手机卡监听器,熔沸点越低,例如:正戊烷>异戊烷>新戊烷   ⑤互为同分异构体的芬芳烃及其衍生物中,窃听器材 │族长大教堂,熔沸点顺序为:邻位化合物>间位化合物>对位化合物分子晶体的结构特点和结构模型  严密沉积方法对照   干冰:范德华力 1个分子四周紧邻12个分子   冰:范德华力、氢键 1个分子周围紧邻4个分子   外观:两者相似 硬度:类似(小) 熔点:干冰比冰小 密度:干冰比冰大
