好久没发了,发个关于化学学习的(有点难度) - 杭潇 - 2005-2-7 What are important for the chemistry students Chapter 1 Skills Knowledge - Level 1 Terminology to recall from your general chemistry class: (Note that your textbook has a glossary with definitions) atomic orbitals: s, p, d molecular orbitals: sigma and pi bonds hybrid orbitals: sp, sp2, sp3 types of bonds: ionic, covalent, polar covalent valence: normal bonding patterns for C, H, N, O, halogens electronegativity: higher to the right and up the Periodic Table functional groups: alcohols, ethers, carbonyls (aldehydes, ketones), carboxylic acids Concepts - Level 2 The Periodic Table: periodic trends in valence, electronegativity, etc. Lewis structures: all electrons shown Kekule structures: lines represent bonds line structures: omit Cs and Hs condensed structures: abbreviations for standard structural units VSEPR: method of identifying preferred 3D structures hybridization: hybrid orbitals allow optimum bonding functional groups: carbon and oxygen bonding patterns, isomerism Applications - Level 3 create appropriate Lewis structures, including formal charges recognize different resonance forms for a given molecule interpret Kekule, line, and condensed structures identify polar bonds and direction of polarity Analytical Skills - Level 4 & higher identify the hybridization of a given atom or a given bond using hybridization or VSEPR, write good 3D structures for molecules - 哈娃~echo - 2005-2-7 晕..看不懂啊..化学学的不好本来想看看怎样学,结果却看不懂.看来我先该好好学英语..~ - 杭潇 - 2005-2-7 呵呵,英语确实是要好好学的~ 不过,也不至于太难吧 至少,没有专业单词吧 - 哈娃~echo - 2005-2-7 学长,你多大我多大啊...我个人认为我英语学成目前这个样子已经不错了吧...~ ![]() - skyhyatt - 2005-2-7 楼主,你大学学的啥专业啊,“化学英语“还是”无机化学“哈哈 - 杭潇 - 2005-2-7 呵呵,楼上的,猜得不错啊:P 我学应化的…… - wǒ僾.o菓涷 - 2005-2-11 一個都不懂 不敢看了 - 杭潇 - 2005-2-11 呵呵,慢慢来,慢慢就懂了 - Nolovable - 2005-2-12 反正我现在也不专攻化学 不用这么麻烦吧.. - 杭潇 - 2005-2-12 主要是这两天不带了译 过两天吧,哪天没事干了,给大家译过来 |
