What is the IUPAC name of the following compound?

Liquids \(\mathrm{A}\) and \(\mathrm{B}\) form an ideal solution. At \(30^{\circ} \mathrm{C}\), the total vapour pressure of a solution containing \(1 \mathrm{~mol}\) of \(\mathrm{A}\) and \(2 \mathrm{~mol}\) of \(\mathrm{B}\) is \(250 \mathrm{mmH} \mathrm{g}\). The total vapour pressure becomes \(300 \mathrm{mmH} \mathrm{g}\) when 1 more mol of \(\mathrm{A}\) is added to the first solution. The vapour pressures of pure \(\mathrm{A}\) and \(\mathrm{B}\) at the same temperature are
