That last problem, with the ring expansion, was absolutely BRUTAL.

If adjacent carbon of carbocation contain two methyl and one phenyl groups then which group shift first? methyl or phenyl?Why? What is the order? Hydride>alkyl>phenyl Or Hydride>phenyl>alkyl ?

thank you!

You're welcome!

How come methanol can deprotonate? I dont understand how that oxygen can make 3 bonds post deprotonation.

Think of protonated methanol as being analogous to protonated water (i.e. hydronium, H3O+). Many alcohols, like methanol, are comparable in acidity and basicity to water. You'll see water and alcohols commonly acting as either acids or bases in a variety of organic reactions. And they are very common in SN1 reactions. In an SN1 reaction you typically have a neutral nucleophile (like water or an alcohol) which will end up positively charged after it attacks the carbocation. A second molecule of water or the acohol will commonly deprotonate it yielding a neutral product. Hope this helps!

@@ChadsPrep Ahhh. This helps so much! And by neutral nucleophile, you mean weak nucleophile. In other words, not as polar.
