1化学 系统命名法CH3CH2CH(CH3)CH2CH(CH3)CH(C2H5)CH2CH3 iupac命名,翻译成中文为:3-乙基-4,6-二甲基辛烷(IUPAC乙基在前) 3,5-二甲基-6-基乙辛烷 3-乙基-4,6-二甲基辛烷 3+5+6> 3+4+6 原则上:位次号之和最小优先 应该为4,6-二甲基-3-乙基辛烷 那这样就与简单支链优先(最低系列)有冲突. ...
1. **确定最长主链**:结构式CH3CH2CH(CH3)CH2CH2CH3的主体为6个连续碳链(CH3-CH2-CH-CH2-CH2-CH3),即己烷。2. **编号方向选择**:从两端分别编号: - 从左端开始,甲基支链位于第3位碳。 - 从右端开始,甲基支链位于第4位碳。 根据“取代基位置最小”原则,选择从左端编号(3 < 4)。3. **命名组合*...

CH3CH2CH2CH(CH3)2 Formulate Compound Name: In organic chemistry, the name of the compound is formatted by checking the type of the compound, whether saturated or unsaturated, because for saturated (alkane) suffix "ane" use and unsaturated (alkene suffix "ene" is used, and for alkyne...
**a) CH3-CH(CH3)-CH2-CH3** 1. **确定主链**:最长碳链为4个碳(丁烷)。 2. **编号取代基位置**:甲基位于主链的第二个碳。无论从左或右编号,取代基位次均为2(最小),故命名为2-甲基丁烷。**b) CH3-CH2-CH(CH3)-CH2-CH3** 1. **确定主链**:最长碳链为5个碳(戊烷)。 2. **编号取代...
根据系统命名法(IUPAC命名法),有机物(CH3)2CHCH(CH2CH3)(CH2CH2CH3)的正确名称是A. 3-异丙基己烷B. 2-甲基-3-丙基戊烷C. 3-乙基丙烷D. 2-甲基-3-乙基己烷 根据系统命名法,可知有机物(CH3)2CHCH(CH2CH3)(CH2CH2CH3)中最长碳链含有6个C,主链为己烷,编号从左边开始,在2号C含有1个甲基,在3号C含有...
