Which of the following cannot be prepared using the Wurtz reaction?

Give the name and use of the compound produced during the incomplete combustion of an alkane.

As the number of carbon atoms in an alkane chain increases,the boiling point...........

The interaction that causes the most instability in the boat conformation of cyclohexane is .......

The correct order of boiling points of the following molecules is:
$(i)$ $n$-Hexane
$(ii)$ $2$-methylpentane
$(iii)$ $2,3$-dimethylbutane

Given below are two statements:
Statement $I$ : The boiling point of three isomeric pentanes follows the order
$n$-pentane $>$ isopentane $>$ neopentane
Statement $II$ : When branching increases,the molecule attains a shape of sphere. This results in smaller surface area for contact,due to which the intermolecular forces between the spherical molecules are weak,thereby lowering the boiling point.
In the light of the above statements,choose the most appropriate answer from the options given below:
