为下列物质命名.(CH3)2 CH-CH2 CH2 C =CH | | CH3 CH3(CH3)2 CH-CH2 CH2 C(CH3)=CH(CH3)
命名下列各有机物①CH2=CH-CH2-CH2-CH3②CH3-CH=CH-CH2-CH3③CH3-CH(上面有一个-CH3)-CH=CH-CH2-CH3④CH3-CH(上面有一个-CH3)-CH(下面有一个-CH3)-CH2-CH=CH2⑤CH3-CH2-CH(上面有一个-CH3-CH2-OH2)-C(下面有一个-C2H5)=CH2
CH3 CH3 CH3-CH-CH2-C=c-CH3 CH2CH2CH3 的系统命名CH3-CH(CH3)-CH2-C(CH2CH2CH3)=C(CH3)-CH3
CH3-CH2-(CH3)C(CH3)-CH(C2H5)-CH3 是什么
CH3-CH2-C-CH-CH3 怎么命名 || | CH2 CH3
1)CH3--CH--CH--CH3| |CH3 CH2|CH3 2)CH3--CH--CH--CH--CH--CH3| | | |CH3 CH3 CH2 CH3|CH33)CH3--CH--CH2--CH3|C2H5CH3--CH--CH--CH3 ..............|...........| ..............CH3...........CH2 ..............| ..................CH3 2)CH3--CH--CH--CH--CH--CH3
CH2=CH-CH=CH2和CH3-CH2-CH2-C-=CH不是同系物咩?
CH3=CH=CH2-O-CH2-CH-CH3是什么
又有烯烃又有炔烃的命名,如下CH3-CH=CH-CH(CH3)-CH2-C三CH-CH3
2-丁烯CH3-CH=CH-CH3 < 异丁烯CH2=C(CH3)2 为啥
CH3C≡CH合成CH2=C(CH3)COOCH3
CH2=CH-CH(CH3)-CH2OH是什么?
求命名:1、CH2=CH-CH2-CH2-CH2-CH2-CH32. CH2-C-CH=CH-CH3 | C2H5 CH3 |3. CH3-C-CH=CH-CH=CH2 | CH3
CH3CH(CH3)C=(CH2)CH2CH3系统命名CH3-CH-C-CH2CH3单 双CH3 CH2
ch3(ch2)2ch3,ch3-ch=c=ch2和ch2=ch-ch=ch用化学方法鉴别
CH2=CH-CH2-CH3是什么
CH4→CH3-CH2-CH=CH2
一个重排反应的问题像+CH2 CH3| |CH3-C-CH2-CH-CH3|CH3重排后为什么是CH3 CH3| |CH3CH2-C-CH2-CH-CH3+而不是CH3 CH3 CH3| | |CH3-C-CH2-CH-CH3+
