答案

结构式不好在屏幕上表示,就提供结构简式吧!
己烷：
CH3-(CH2)4-CH3
CH3CH(CH3)-(CH2)3-CH3
CH3CH2CH(CH3)-(CH2)2-CH3
CH3CH(CH3)CH(CH3)CH2CH2CH3
CH3CH(CH3)CH2CH(CH3)CH2CH3
CH3CH(CH3)CH2CH2CH(CH3)CH3
CH3CH(CH3)CH(CH3)CH(CH3)CH3
庚烷：
CH3-(CH2)5-CH3
(CH3)2-CH-(CH2)3-CH3
CH3CH2CH(CH3)CH2CH2CH3
(CH3CH2)3CH
(CH3)3-C-CH2CH2CH3
(CH3CH2)2-C-(CH3)2
(CH3)2-CH-CH(CH3)-CH2CH3
(CH3)2-CH-CH2-CH-(CH3)2
(CH3)3-C-CH-(CH3)2
