Problem: Which of the following is less soluble in hexane, methanol or CH3Br(l). Don't try to type the subscripts, just use letters and numbers.A. methanolB. CH3Br(l)C. methanol and CH3Br(l) are equally soluble in hexaneD. none of them would be soluble in hexane

FREE Expert Solution

We’re being asked identify which among methanol or CH3Br(l) is less soluble in hexane. Recall that the main idea in dissolution is like dissolves like, which means compounds with the same polarity and intermolecular force can dissolve each other.


Hexane is an example of a hydrocarbon, a compound composed only of carbons and hydrogens. Hydrocarbons are nonpolar compounds. This means that hexane is a nonpolar molecule that exhibits dispersion forces


So for this, we need to draw the Lewis structures of the given choices and determine their polarity.

Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present and draw the Lewis structure for the molecule.

Step 3: Determine the polarity of the molecule.
