Quizplus · Accepted Answer

i. $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{3}$ is butane, a straight-chain alkane with four carbon atoms. ii. $\mathrm{CH}_{3} \mathrm{CHCH}_{3}$ with a $\mathrm{CH}_{3}$ branch is isobutane, an isomer of butane. iii. $\mathrm{CH}_{3} \mathrm{CCH}_{3}$ with two $\mathrm{CH}_{3}$ branches on the same carbon is neopentane, the most branched isomer of pentane.
