When - butane is heated in the presence of it will be converted into
1 Ethane
2 Propane
3 Butene
4 Isobutane
Explanation:
In the presence of if any alkane having more than four carbon is heated, then isomerisation takes place

Assertion : Methane does not react with in dark. Reason : It is a free radical substitution.
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.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Chlorination of methane is a free radical substitution. To convert molecules into chlorine free radicals, energy is required which is not available in dark. Thus, methane does not react with in dark due to no formation of free radicals. So, option (2) is correct.

Assertion : Order of reactivity of alkanes is . Reason : Reactivity depends upon the effect of the alkyl group.
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.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The order of reactivity of primary , secondary and tertiary alkanes is . Greater the number of alkyl groups present, higher is the reactivity. Alkyl groups have effect. So, option (3) is correct.

Statement A : Iodination of alkanes is reversible. Statement B : Iodination is carried out in presence of iodic acid.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
Iodination is reversible since formed is a strong reducing agent and reduces the alkyl iodide back to alkane. Iodination can be done only in presence of strong oxidising agents like iodic acid which destroys the hydriodic acid.
