Comparing Methane and Methanol
Why is methane a gas at room temperature and methanol a liquid?
Take a look at the electrostatic potential map of the molecules below showing charge distribution. The red indicates a region with a negative charge and the blue indicates a positive charge.
The methane molecule has an overall white color - what does this indicate?
The methanol molecule has a region of blue and a region of red indicating that the charge is unevenly distributed - the molecule is polar.
