Why an anti-addition is formed once the acid protonates an oxygen in a ring opening reaction with epoxides and why a trans diol is the only thing that can be formed. When you prepare an epoxide using an acid it gives a trans diol. Why do epoxides open in an SN1 like fashion when a carbocation is not even fully formed, producing a less substituted alcohol when an SN2 gives you the same product with a more substituted alcohol
