Correct Answer - `{:(" "CH_(3)),(" "|),(CH_(2)=C-CH_(2)-CH_(3)):}" "`2-Methylbut-1-ene
`{:(" "CH_(3)),(" "|),(CH_(3)-C=CH-CH_(3)):}" "`2-Methylbut-2-ene
`{:(" "CH_(3)),(" "|),(CH_(3)-CH-CH=CH_(2)):}" "`3-Methylbut-1-ene
The basic skeleton of 2-methylbutane is shown below:
`overset(1)C-underset(C)underset(|)overset(2)C-overset(3)C-overset(4)C`
On the basis of this structure, various alkenes that will give 2-methylbutane on hydrogenation are:
(a) `H_(3)-underset(CH_(3))underset(|)"CH"-CH=CH_(2)`
(b) `CH_(3)-overset(CH_(3))overset(|)C=CH-CH_(3)` (c) `CH_(2)=underset(CH_(3))underset(|)C-CH-CH_(3)`
