Final answer:The compounds ranked from most acidic to least are as follows: CH3OH/2CH3OH, CH3NH2. This ranking is based on their respective pKa values, which indicate the strength of an acid in a solution.Explanation:The acidity of compounds is determined by theirpKa value, a logarithmic scale that measures the strength of an acid in solution. In this context, the lower the pKa, the stronger the acid.The pKa of CH3NH2 is 38, thepKa of CH3OH(methanol) is 15.5, and the pKa value for2CH3OHwould be equivalent to that of a single CH3OH molecule.Therefore, ranking these compounds from most acidic to least, we would have:CH3OH / 2CH3OHCH3NH2Note that CH3OH and 2CH3OH are equivalent in terms of acidity.Learn more about Acidity Ranking here:brainly.com/question/32813654#SPJ6...
