in chemistry lab one of our post lab questions is to design a mechanism for the dehydration of 1-methyl-1-cyclohexanol. Then I need to see if the reaction is faster or slower than the one i performed in lab

  • Your alcohol group is tertiary so this is a classic Sn1 mechanism. I assume you are using an acid catalyst because it won’t work otherwise. A proton from the acid protonates the alcohol giving a positively charge OH2 group. This can leave as a stable water molecule creating a tertiary cation intermediate on the carbon it just left. There are two possible hydrogens that can now be eliminated to give the alkene and Zaitsef’s rule indicates that you will get the most substituted alkene. A hydrogen on a CH2 group in the ring adjacent to the cationic center will be removed and the electrons that form that C-H bond will moved into the ring creating a tri-substituted double bond.

  • it style of feels to be in keeping with an early Tribulation Epistle, which Peter is (a million puppy a million). he’s addressing this to the “strangers” and that could flow with those Rev 7 a hundred and forty four,000. here Peter is exhorting them in the time of the witness of Christ at the same time as He grew to become into in the flesh (human flesh – no longer the physique he’s in now – you’re version has it incorrect) that as He suffered and went via it, then you quite may additionally flow via this time of Tribulation. in case you undergo in suggestions that the Books commencing with Hebrews is written for people who’re getting into the time of the Tribulation and the delivery pangs of the Millennium then that’s going to become much less mysterious.
