Problem: Compare the processes that occur when methanol (CH3OH), hydrogen chloride (HCl), and sodium hydroxide (NaOH) dissolve in water. Write equations and prepare sketches showing the form in which each of these compounds is present in its respective solution.

FREE Expert Solution

We’re being asked to compare the processes that occur when methanol (CH3OH), hydrogen chloride (HCl), and sodium hydroxide (NaOH) dissolve in water.


Recall the Lewis structure of water (H2O): 

Since hydrogen is bonded directly to oxygen, an electronegative atom, we can say that water is a polar molecule that exhibits hydrogen bonding.


Now let's draw the Lewis structure of each compound and check how each of the given compounds will interact with water:

For CH3OH:

Step 1: Carbon is less electronegative than oxygen so carbon is the central atom. Recall that hydrogen cannot be a central atom.
