The van der Waal equations for 'n' moles of a real gas is $ \bigg( p+ \large\frac{a}{V^2} \bigg) (V-b)=nRT$ where P is pressure, V is volume, T is absolute temperature, R is molar gas constant and a, b, c are Van der Waal constants.The dimensional formula for ab is

$\begin {array} {1 1} (1)\;ML^8T^{-2} & \quad (2)\;ML^6T^{-2} \\ (3)\;ML^4T^{-2} & \quad (4)\;ML^2T^{-2} \end {array}$
