问题描述：
cH3-CH(C2H5)-CH(CH3)(C2H5)-CH3的名称
答
CH3-CH(C2H5)-CH(CH3)(C2H5)-CH3的结构可能存在么？左边的CH3-CH(C2H5)-正确，但右边的-CH(CH3)(C2H5)-CH3是怎么回事？是-C(CH3)(C2H5)-CH3还是-CH(CH3)(C2H4)-CH3？
答
3,3,4-三甲基-己烷
答
cH3-CH(C2H5)-CH(CH3)(C2H5)-CH3的写法有误
可能原题是这样的：cH3-CH(C2H5)-C(CH3)(C2H5)-CH3或cH3-CH(C2H5)-CH(CH3)C2H5-CH3
cH3-CH(C2H5)-C(CH3)(C2H5)-CH3：3,3,4-三甲基己烷
cH3-CH(C2H5)-CH(CH3)C2H5-CH3：3,4-二甲基庚烷
答
3,3,4-三甲基己烷 ；甲基与乙烷之间不要加 “-”
