2008年10月11日 · ch3ch(ch2ch3)ch3叫乙基丙烷，括号里表示支链。 你看括号里的原子团：两个碳原子五个氢原子，则只有一个连接键了，也就只能做支链了。 已赞过 已踩过

There are 4 easy steps to find the molar mass of CH3 (CH2)2CH3 based on its chemical formula. 1. Count The Number of Each Atom. The first step to finding the molar mass of Butane is to count the number of each atom present in a single molecule using the chemical formula, CH3 (CH2)2CH3: 2. Find Atomic Mass of Each Element.

Calculate molar mass of each element: multiply the atomic mass of each element by the number of atoms of that element in the compound. Add them together: add the results from step 3 to get the total molar mass of the compound. Carbon (C) has an atomic mass of about 12.01 amu. Oxygen (O) has an atomic mass of about 16.00 amu.

Enter an equation of a chemical reaction and click 'Balance'. The answer will appear below. Always use the upper case for the first character in the element name and the lower case for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - …

CH3(CH2)2CH3 + O2 = CO2 + H2O is a Combustion reaction where two moles of Butane [CH 3 (CH 2) 2 CH 3] and thirteen moles of Dioxygen [O 2] react to form eight moles of Carbon Dioxide [CO 2] and ten moles of Water [H 2 O]

For example, we can represent pentane (CH 3 CH 2 CH 2 CH 2 CH 3) and isopentane [ (CH 3) 2 CHCH 2 CH 3] as follows: Parentheses in condensed structural formulas indicate that the enclosed grouping of atoms is attached to the adjacent carbon atom. Below is an example of a more complicated molecule.

[解答]解:(1))(ch3)2ch(ch2)2ch(c2h5)(ch2)2ch3,最长的碳链含有8个c,主链为辛烷,编号从左边开始,满足取代基编号之和最小,在2号碳上有1个甲基、5号c有1个乙基,该有机物命名为:2﹣甲基﹣5﹣乙基辛烷,故答案为:2﹣甲基﹣5﹣乙基辛烷;(2),最长的碳链含有8个c,主链为辛烷,编号从 ...

2018年4月8日 · CH3CH2C（CH2CH3）2CH2CH3的名称为3，3-二甲基戊烷。 烷烃 的命名原则是：找出最长的碳链当主链，依碳数命名主链，前十个以天干 (甲、乙、丙...)代表碳数，碳数多于十个时，以 中文数字 命名，如：十一烷；从最近的取代基位置编号：1、2、3... (使取代基的位置数字越小越好)。 以数字代表取代基的位置。 数字与中文数字之间以－ 隔开；有多个取代基时，以取代基数字最小且最长的碳链当主链，并依甲基、乙基、丙基的顺序列出所有取代基；有两个 …
