Which of the following order of dipole moment for stated molecules is correct?

Calculate the compressibility factor of $1$ mole of a certain real gas if it occupies $0.4 \text{ dm}^3$ at $300$ K and $40$ atm. [R $= 0.082$ atm $\text{dm}^3 \text{K}^{-1}\text{mol}^{-1}$]

$\text{C}_2\text{H}_5\text{OH}(l) + 3\text{O}_2(g) \rightarrow 2\text{CO}_2(g) + 3\text{H}_2\text{O}(l)$
The value of enthalpy change ($\Delta H$) for above reaction at $27\,^\circ\text{C}$ is $-1366.5$ kJ $\text{mol}^{-1}$. Then value of internal energy change for the same reaction at this temperature will be

Which of the following processes has $\Delta S$ negative?
