 I know anyways let's try this let's try this one it says draw the mechanism in organic products of the following SN1 reaction and predict whether each product you draw is major or minor so that already gives you kind of a clue as to what you may be thinking that you might be getting in an SN1 reaction maybe two different products okay not necessarily all SN1 reaction but it does tell you that it's an SN1 reaction so that's kind of nice you know that it's going to be substituting something for something else okay so normally in an organic chemistry reaction you have two different types of molecules right what are those two types of molecules do you guys remember anyway an electrophile right so we probably want to find those things and we know in substitution reactions we do have those things right so do you remember in the substitution reaction what's the common electrophile hydroxide well so that's the nucleophile right yeah so the electrophile is the alkyl halide in the substitution remember so it's the thing with the good leaving you recall that the thing with the good leaving okay so this is a secondary alkyl halide that's good because we know primaries don't go through SN1 reactions okay so it has to be there a secondary or tertiary to do it you also have to have remember a polar product solvent something that's going to pull the the iodide from the alkane portion of the alkyl halide okay so it's going to help it separate in this reaction the solvent is actually cyclohexanol there that's the name of that molecule so notice hopefully guys you notice this really kind of looks a lot like water right if you cover that up you might not know if it's water or not right so it's water with instead of two hydrogens a cyclohexane ring has been substituted for one of the hydrogen so it has similar properties to water okay so water is a good polar product solvent remember for SN1 reactions it was good so this has similar properties to that so it influences this to separate or what we say in terms of these substitution reactions the leaving group to leave right you guys remember that so what's the leaving group here you guys remember all right yeah so how do we show that so that currently are right there does does the solvent participate in the first step of the SN1 reaction not fun in fact the SN1 reactions rate determining step is the first step you guys remember that what would be the rate equation for an SN1 reaction so rate equals k times the concentration of rx so nothing else is influencing the rate except for the alkyl halide so it's on camera okay so in fact I'm just going to erase this for right now okay and put it into the second step so first step is over let's draw the products of that first step what is the intermediate of these SN1 reactions Paul so that's what we have right hopefully that's what you drew somebody get the door okay so what is the hybridization of that carbon remember sp2 right because it's only got how many electron groups are three right so it's trigonal planar right so the nucleophile well I gave it away I was gonna ask eventually what this was this is the letter file but the nucleophile will be able to attack it from either the front face or the back face you guys remember when you have a planar molecule you can do that so I only see two bonds here what's the other bond yeah so if you want to you can explicitly show that you don't have to okay so now we're going to introduce the nucleophile so this is the electrophile short-hand purple cat irons are always electrophiles the nucleophile was the nucleophile in the SN1 range well in that other one we saw but in this one it's what well you don't have to say the name but what was it it's the solvent right it's the solvent so in this case cyclohexanol was the solvent you should know that the name of that molecule if you don't know it now you do okay so this is the nucleophile right we said so the nucleophile attacks the electrophile right so what portion of the nucleophile is going to attack it the long patch yeah of course right crazy right yeah look at me like of course the long yeah no lie that's what I say okay so so remember we said oftentimes you'll get two products from an SN1 reaction right because they can attack from the front face or from the back face do you guys recall that and this in this particular instance are you going to get two products why not yeah so the molecule that you're going to be forming is a chiral because two well we'll draw it to the groups to the groups that that carbon is attached to the same thing to the cyclopentane if you want you can still draw that hydrogen if it makes you feel more comfortable no problem so is that the end of the reaction what do we have to do okay yeah let's identify this right so this is the leading group why do we call it the leading group because it's left right but can we isolate this molecule here what do we have to do to it yeah deprotonated right so what's going to be the thing that deprotonates it solvent the solvent right it's swimming in a sea of cyclohexanol so there's a lot of it around so I would have to in an SN1 reaction or I could give you the reactants and products and you would tell me to solve them potentially I would have prepared for it before I okay so let's just draw the product hopefully you guys have drawn it already and just confirm it oftentimes these react these questions will ask you to put a box around the organic product see if we're still in camera of course if you wanted to draw the protonated solvent okay so there's only the one organic product in this reaction yeah question no question you sure well you don't need to in things that are a chiral okay so it's oftentimes better to not put those if you have no stereocenters in your molecule I would recommend you don't put wedges and dashes any other question
