The major product obtained in the photo catalysed bromination of 2-methylbutane is
1 1-Bromo-2-methylbutane
2 1-Bromo-3-methylbutane
3 2-Bromo-3-methylbutane
4 2-Bromo-2-methylbutane
Explanation:
The order of substitution in different alkanes is \(3^\circ > 2^\circ > 1^\circ \) Thus the bromination of 2- methyl butane mainly gives 2-Bromo -2-Methyl butane
JEE - 2014
CHXI13:HYDROCARBONS

Assertion : During free radical chlorination of butane, some ethane is also formed as by product. Reason : Disproportion is a characteristic of a free radical intermediate.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.

In the halogenation of methane, which of the following intermediate reaction does not take place?
In the halogenation of methane, the following intermediate reaction does not take place : \(\mathrm{Cl}^{\bullet}+\mathrm{CH}_{4} \rightarrow \mathrm{CH}_{3} \mathrm{Cl}+\mathrm{H}^{\bullet}\) Due to high energy of activation the above reaction does not proceed.

Which of the following is called marsh gas?
1 \(\mathrm{C}_{2} \mathrm{H}_{4}\)
2 \(\mathrm{C}_{2} \mathrm{H}_{6}\)
3 \(\mathrm{C}_{2} \mathrm{H}_{2}\)
4 \(\mathrm{CH}_{4}\)
Explanation:
Methane is called marsh gas because it is found in swamps or marshy places and can be obtained by bacterial decomposition of fossils of plants and animals.
