Boiling point of any molecule depends on 2 things ( in the same priority order as they are mentioned)
1) The strength of inter-molecular forces between the molecules.
2) Molar mass or surface area of the molecules.
Since stronger is the inter-molecular forces between the molecules, more will be the energy required to break the inter-molecular forces.
Hence more will be the boiling point of the molecule.
Similarly more is the mass of the compound, more will be the energy required to boil.
Hence more will be the boiling point of the compound.
Since all the molecules have 6 carbons and 14 hydrogens only (C-H bonds are not shown in line diagram).
Hence the molecular formula of all the 3 compounds is C6H14.
Since all the 3 molecules have same molecular formula but different structural formula.
Hence the 3 molecules given are constitutional isomers.
Hence statement I is correct.
The IUPAC name of molecule A is hexane, molecule B is 2,3-dimethyl butane and molecule C is 2-methyl pentane.
Hence the structure C is properly named as 2-methyl pentane and not hexane.
Hence statement II is incorrect.
