12、质的命名,Part 4 Nomenclature Of Inorganic Chemicals,element,compound,4.1 元素和单质的命名,“元素”和“单质”的英文意思都是“element”,有时为了区别,在强调“单质”时可用“free element”。因此,单质的英文名称与元素的英文名称是一样的。下面给出的既是元素的名称,同时又是单质的名称。,S-block Element,IAHydrogenLithiumSodiumPotassium RubidiumCesiumFrancium,IIABerylliumMagnesiumCalciumStrontiumBariumRa

14、se Cu:copper Zn:zinc Hg:mercury Ag:silver Au:gold,4.2化合物的命名,化合物的命名顺序都是根据化学式从左往右读,这与中文读法顺序是相反的。表示原子个数时使用前缀:mono-di-tri-tetra-penta-hexa-hepta-octa-,nona-,deca-,但是在不会引起歧义时,这些前缀都尽可能被省去。,1 化合物正电荷部分的读法,直呼其名,即读其元素名称。如CO:carbon monoxide Al2O3:aluminium oxide N2O4:Dinitrogen tetroxide(tetra-,mono-后缀中的a,o在后一
15、o之前省去)对于有变价的金属元素,除了可用前缀来表示以外,更多采用罗马数字来表示金属的氧化态,或用后缀-ous表示低价,-ic表示高价。如 FeO:iron(II)oxide 或 ferrous oxide Fe2O3:iron(III)oxide或ferric oxide Cu2O:copper(I)oxide 或cuprous oxide CuO:copper(II)oxide或cupric oxide,化合物负电荷部分的读法:,.二元化合物.非金属氢化物.无氧酸.含氧酸与含氧酸根阴离子.盐,二元化合物,常见的二元化合物有卤化物,氧化物,硫化物,氮化物,磷化物,碳化物,金属氢化物等,命名时
16、需要使用后缀-ide,如:fluoride,chloride,bromide,iodide,oxide,sulfide,nitride,phosphide,carbide,hydride;OH-的名称也是用后缀-ide:hydroxide,非金属氢化物不用此后缀,而是将其看成其它二元化合物(见4.),非最低价的二元化合物还要加前缀,如O22-:peroxide O2-:superoxide举例:NaF:sodium fluorideAlCl3:aluminium chloride Mg2N3:magnesium nitride Ag2S:silver sulfide CaC2:calcium
17、carbide Fe(OH)2:iron(II)hydroxide 有些物质常用俗称,如NO nitric oxide N2O nitrous oxide,4.2 非金属氢化物,1)除了水和氨气使用俗称water,ammonia以外,其它的非金属氢化物都用系统名称,命名规则根据化学式的写法不同而有所不同。对于卤族和氧族氢化物,在化学式中写在前面,因此将其看成另一元素的二元化合物。举例:HF hydrogen fluoride HCl hydrogen chloride HBr hydrogen bromide HI hydrogen iodide H2S hydrogen sulfide H2
18、Se hydrogen selenide H2Te hydrogen telluride 2)对于其它族的非金属氢化物,在化学式中写在后面,可加后缀ane,氮族还可加-ine 举例:PH3:phosphine或phosphane AsH3:arsine或arsane SbH3:stibine或stibane BiH3:bismuthane CH4:methane SiH4:silane B2H6:diborane,4.无氧酸,命名规则:hydro-词根-icacid 举例:HCl:hydrochloric acid H2S:hydrosufuric acid,Symbol Element St
19、em Binary name endings,4.含氧酸与含氧酸根阴离子,化学专业英语用前后缀的不同组合显示不同价态的含氧酸和含氧酸根阴离子,价态相同的含氧酸及含氧酸根阴离子具有相同的前缀,不同的后缀。高某酸 per-ic 正酸 ic 亚酸-ous 次酸 hypo-ous高某酸根 per-ate 正酸根 ate 亚酸根-ite 次酸根hypo-ite其它的前缀还有 ortho-正 meta-偏 thio-硫代举例:HClO4 perchloric acid ClO4-perchlorate ion HClO3 chloric acid ClO3-chlorate ion HClO2 chlor
20、ous acid ClO2-chlorite ion HClO hypochlorous acid ClO-hypochlorite ion H2SO4 sulfuric acid H2SO3 sulfurous acid HNO3 nitric acid HNO2 nitrous acid HPO3 metaphosphoric acid S2O32-thiosulfate ion,4.盐,正盐:根据化学式从左往右分别读出阳离子和阴离子的名称。如FeSO4 iron(II)sulfate KMnO4 potassium permanganate酸式盐:同正盐的读法,酸根中的读做hydroge
21、n,氢原子的个数用前缀表示。如NaHCO3:sodium hydrogencarbonate 或 sodium bicarbonate NaH2PO4:sodium dihydrogenphosphate,复盐:同正盐的读法,并且阳离子按英文名称的第一个字母顺序读。如 KNaCO3:potassuim sodium carbonateNaNH4HPO4:ammonium sodium hydrogenphosphate水合盐:结晶水读做water或hydrate如AlCl36H2O:aluminum chloride 6-water 或aluminum chloride hexahydrate
22、 AlK(SO4)212H2O aluminium potassium sulphate 12-water,有机物质的命名,烷烃的英文命名,1)烷烃(Alkanes),有机化合物的英文命名很不统一,有普通命名、衍生命名、系统命名及CA系统命名等。,烷烃的英文名称字尾都有-ane,2 不饱和烃Unsaturated Hydrocarbon,CH3甲 基 methyl methylCH3CH2乙 基 ethyl ethylCH3CH2CH2正丙基n-propyl propyl异丙基isopropyl(1-methyl ethyl)CH3CH2CH2CH2 正丁基n-butyl butylCH3(C
23、H2)3CH2 正戊基n-pentyl或n-amyl pentyl异戊基isopentyl或isoamyl(3-methyl butyl)新戊基neopentyl(2,2-dimethyl propyl),烷基的名称,CH2=CH2 乙 烯 ethylene ethylene,CH3CH=CH2 丙 烯 propylene propene,1丁烯1-butylene 1-butene,(CH3)2C=CH2 异丁烯isobutylene propene,2methylCH3CH2CH2CH=CH2 1戊烯1-amylene 1-pentene,异戊二烯isoprene 1,3butadiene
24、,2-methyl-烯基(alkenyl)是将烯的字尾-ene 改为-enyl。,烯类化合物的名称,烯基的名称,CH2=CH 乙烯基vinyl ethenyl烯丙基allyl(2-propenyl)丙烯基propenyl(1-propenyl)2-丁烯基(2-butenyl),炔类化合物的名称,HCCH 乙炔 acetylene;ethyne,CH3CCH 丙 炔 methyl acetylene;propyne,2丁炔dimethyl acetylene;2-butyne,丙烯基乙炔propenyl acetylene;3-penten-1-yne,系统命名是以芳香环为母体,取代基根据环上的
