Iodination of a hydrocarbon $(C-H \rightarrow C-I)$ with molecular iodine is a slow and reversible reaction. However,it can be carried out in the presence of an oxidizing agent such as

$n$-pentane and isopentane can be distinguished by

What are $X$ and $Y$ in the following reaction sequence?
Iso-pentane $\xrightarrow{KMnO_4} X$ $\xrightarrow[358 \ K]{20 \% H_3PO_4} Y$

If a mixture of methyl iodide and ethyl iodide in equal proportions is treated with metallic sodium in dry ether,the number of possible products obtained will be ....................

What is the number of moles of $sp^2$ hybridized carbon atoms present in $n$ moles of isopentane?

Propane molecule on chlorination under photochemical conditions gives two dichloro products,$x$ and $y$. Amongst $x$ and $y$,$x$ is an optically active molecule. How many trichloro products (consider only structural isomers) will be obtained from $x$ when it is further treated with chlorine under photochemical conditions?
