(CH3)3CCH=CHCH3(\text{CH}_3)_3\text{CCH=CHCH}_3(CH3)3CCH=CHCH3
(CH3)2C=CHCH2CH2CH3(\text{CH}_3)_2\text{C=CHCH}_2\text{CH}_2\text{CH}_3(CH3)2C=CHCH2CH2CH3
(CH3)3CCH2CH=CH2(\text{CH}_3)_3\text{CCH}_2\text{CH=CH}_2(CH3)3CCH2CH=CH2
CH2=C(CH3)CH2CH(CH3)2\text{CH}_2\text{=C(CH}_3)\text{CH}_2\text{CH(CH}_3)_2CH2=C(CH3)CH2CH(CH3)2
