backside attack example sentences

5) What kind of stereochemistry do we expect in that sort of substitution?--backside attack gives us inversion of stereochemistry. 2404

example sentences with backside

15) Sn1 means carbocation; because our leaving group is on a tertiary carbon, then that for sure tells me right off the bat, I cannot do a backside attack ; I can only do a carbocation. 4213

16) We will learn very shortly that we would describe this as a weak nucleophile; and a weak nucleophile, what do you think about that backside attack ? 4047

17) Where does the nucleophile have to approach?--backside attack ; it has to come from behind the molecule; so we need to draw that as a dashed bond here. 3958

18) Tell me about backside attack ; is backside attack okay for a secondary?--it is actually; it is not great but it is possible; so Sn2 is okay. 3855

19) Tell me about backside attack; is backside attack okay for a secondary?--it is actually; it is not great but it is possible; so Sn2 is okay. 3855

20) This substrate looks like it loves to do Sn2 reactions; do we have a strong nucleophile?--if you want to do backside attack, you need to have a strong nucleophile. 3741

21) How about Sn2?--Sn2 is the single-step mechanism that was backside attack ; so if you remember that the Sn2 is about backside attack, that is going to explain a lot of things such as sterics. 3676

22) How about Sn2?--Sn2 is the single-step mechanism that was backside attack; so if you remember that the Sn2 is about backside attack, that is going to explain a lot of things such as sterics. 3676

23) backside attack where the nucleophile attacks the carbon, kicks out the leaving group?--does that seem reasonable in this case? 2563

24) We would describe this as an intramolecular Sn2 or a backside attack ; an intramolecular backside attack where my O - attacks the carbon, kicks off the leaving group. 2367

25) We would describe this as an intramolecular Sn2 or a backside attack; an intramolecular backside attack where my O - attacks the carbon, kicks off the leaving group. 2367

26) How could I do backside attack on this molecule?--I would have to be coming in through the plane of the benzene ring in order to do that backside attack; it is impossible. 2221

27) How could I do backside attack on this molecule?--I would have to be coming in through the plane of the benzene ring in order to do that backside attack ; it is impossible. 2221

How to use backside in a sentence

28) We will keep that in mind when it comes to backside attack, this rate based on sterics; and tertiary and neopentyl are going to be so slow that we say no reaction. 1029

29) The nucleophile coming in... the nucleophile coming in has to come in from opposite the bromine; this is what we called backside attack . 0891

30) We have seen Sn2 mechanisms, backside attack, where our nucleophile comes in in a single step, kicks out a leaving group. 4165

31) What size ring would this form?--one, two, three, four, five; is a five-membered ring acceptable for doing an intramolecular backside attack ?--it is very good; five and six are both great. 0961

32) We know that for backside attack, steric hindrance is very important; we want to consider those; in terms of steric hindrance, which of these syntheses would be better? 0674

33) Since the epoxide is a wedge, that means the new oxygen has to come in from behind to do backside attack ; it must come in as a dash. 5147

34) Furthermore the O - is a wedge and the bromine is a dash; which means when we want to do a backside attack, we are perfectly set up stereochemistry to do that anti attack. 4988

35) Tell me about the stereochemistry of that group; it has to be backside attack ; if the epoxide is sticking out, that means the deuterium comes from behind. 4797

36) The stereochemistry of the mechanism is what gives evidence that it is an Sn2; remember we observe backside attack ; we observe inversion of stereochemistry. 4520

37) How do I know it is Sn2 here?--how do I know it is backside attack and not a stepwise where the ring opens and then the nucleophile adds in? 4511

38) Shouldn't I have drawn it down here because it is backside attack ?--yes, except no stereochemistry has been shown for this starting material. 4340
