Common substituents(常见取代基): alkyl(烷基), alkenyl(烯基), alkynyl(炔基) groups: Alkyl — omit(省略) the suffix “ane” and add “yl” to the end of the name 烷基—省略后缀“ane” ,将“yl” 加在名称之后 methyl(甲基) – nonadecyl(十九基 )– icosyl(二十 基)

4. A class of compounds in which such prefixes are seldom used is that in which the metal atom usually exhibits(展现) only one oxidation state. 当化合物中的金属元素仅有一种价态,通常很少 加前缀 ZnBr2 zinc bromide CaH2 calcium hydride Na2O sodium oxide Al2S3 aluminum sulfide
I. Nomenclature of inorganic compounds
5. Three elements present, such compounds are named by combining the suffix “-ate” with the name of the less electronegative of the two nonmetallic elements. And “-ite”, “-ate” are used to denote the lower and higher oxidation state of the same electronegative element. 含三种元素的化合物是通过在两种非金属元素中电负性较弱的一 种之后加后缀“-ate” 来命名的。对于电负性相同的元素,用 “-ite”表示低价元素,用“-ate” 表示高价元素 NaNO3 sodium nitrate NaNO2 sodium nitrite

“-ous”, “-ic” were also used to denote (表示) the lower and higher metallic state. 用“-ous”表示低价化合物,用“-ic” 表示高价 化合物

I. Nomenclature of inorganic compounds
When there are more than two oxidation states of the electronegative element, prefix used. The prefix “hypo-” meaning “below”, is used in the name of the lowest oxidation state. The prefix “per-” meaning “hபைடு நூலகம்ghest”, is used when it is in the highest oxidation state. 当电负性较低的元素有超过两种价态时,就使用前缀。 前缀“hypo-” 表示“低于”,用于低价态之前;前 缀“per-” 表示“高于”,用于高价态之前

The
names of linear alkanes, alkenes and alkynes(线型烷烃、烯烃、炔烃的命名): Suffix Methane(甲烷) ~ Icosane(二十烷) (C1 ~ C20 alkanes) ---ane ethene (乙烯)~ Icosene(二十烯) (give position of C=C)---ene

2. If there are only two elements in the compounds(化合物), it is customary (习惯上) to name the more metallic(金属性) element first and the less metallic, or more electronegative(电负性) element second, with the suffix(后缀) “ide”. 若化合物中仅有两种元素,习惯上先命名金属性强的元素,后命名金属性弱的 元素,再加上ide作为后缀 K potassium Na sodium Ca calcium Ba barium S sulfur H hydrogen Cl chlorine Br bromine O oxygen I iodine
