Methane and ethane both can be prepared in one step by which of the following compounds?

Out of the following fractions of petroleum,which one has the lowest boiling point?

Consider the following reaction sequence and identify the major product $P$.
$CH_3CH_2OH$ $\xrightarrow[(ii) KMnO_4]{(i) Jones' Reagent}$ $\xrightarrow[(iii) NaOH, CaO, \Delta]{} P$

Among the following reactions,the reaction that "does not" give an alkane product is:

In the synthesis of sodium lauryl sulphate,lauryl alcohol is treated with $H_2SO_4$ to form lauryl hydrogen sulphate,which is then neutralized with $NaOH$. The structure of lauryl alcohol is $CH_3(CH_2)_nCH_2OH$. What is the value of '$n$'?

$100 \ mL$ of $0.1 \ M$ acetic acid is completely neutralized using a standard solution of $NaOH$. The volume of ethane obtained at $STP$ after the complete electrolysis of the resulting solution is (in $mL$)
