I have researched three books: Brown's, Solomons' and Wade's. I could not find enough information about this.
My prof. says that secondary alkly halides undergo SN1 only under acidic environments.
I think these are the missing structures.
Now, I am wondering, did Sn2 occur here, if yes, at what rate? Was it more important than Sn1? What was the major pathway?
What is the major pathway for all secondary alkyl halides with acidic environment and with NONacidic environments?
Could anyone also just check my missing structures?
