    if reaction takes place in the presence of pyridine then it is SN2 reaction and result is inversion. check it

    only In case of sncl2 sni occurs or in other case

    eduncle-logo-app

    SOCl2

    eduncle-logo-app

    sry only socl2 or any other

    eduncle-logo-app

    only SoCl2

    eduncle-logo-app

    Don't be confused if you reaction of alcohol with SOCl2 the replace OH with Cl but remember stereochemistry of Cl will be same as in OH

    eduncle-logo-app

    if Py also given then stereochemistry of Cl will be reversed of OH

    eduncle-logo-app

    only these things na

    eduncle-logo-app

    yes

    eduncle-logo-app

    please mark best if you like

    eduncle-logo-app

    but intermidiate is ion pair

    eduncle-logo-app

    no simun, ion pair are different thing

    eduncle-logo-app

    just like carbocation, carbanion,free radical are intermediate

    eduncle-logo-app

    can u explain the intermidiate of sni reaction by drawing it

    eduncle-logo-app

    check it

    eduncle-logo-app

    means the intermidiate is carbocation

    eduncle-logo-app

    How many steeps are their

    eduncle-logo-app

    yes, here carbocation is intermediate

    eduncle-logo-app

    so it is same as sn1

    eduncle-logo-app

    in this case rearrangment will occur or not

    reaction of alcohol with SOCl2 is known as SNi. here retaintion in the configuration takes place and alkyl halide is formed

    cropped2451018772944822817.jpg
    eduncle-logo-app

    here carbocation intermediate is formed

    eduncle-logo-app

    reaction sni is only for socl2 or any other

    eduncle-logo-app

    the intermediate is ?tell me something about intermidiate

    eduncle-logo-app

    intermediate is short lived special will convert to product

    check it Simun for nucleophilic substitution

    eduncle-logo-app

    Simun check it. it's very good notes for ArSN

    eduncle-logo-app

    and please accept the and if you got it๐Ÿ™

    eduncle-logo-app

    ok

    eduncle-logo-app

    can u simply explain what's sni condition ...what is the intermediate product what is the catalytic

    eduncle-logo-app

    what its use in question

    eduncle-logo-app

    rate of reaction

    eduncle-logo-app

    yes

    eduncle-logo-app

    I've sent you SNi in simple manner check it and if any doubt you can discuss

    check this simun

    eduncle-logo-app

    please check it and if you like then mark the answer ๐Ÿ˜Š๐Ÿ™

    eduncle-logo-app

    simun see best example of Sni is substitution of OH group using thionyl chloride SOCL2...stereo- retention of configuration...also called intramolecular substitution reaction, ion pair is formed in inetermediate...

    eduncle-logo-app

    simun best and only example which you have to read in higher class too is reaction with thionyl chloride

    eduncle-logo-app

    so read this....i have sent u some video link too and some notes...please read it ...it surely helps..andif helps please mark thank you and appreciate little bit teacher's effort๐Ÿ™๐Ÿ™

    eduncle-logo-app

    but ionpair is not an intermidiate

    eduncle-logo-app

    see simun mechanism above...ion pair is formed in the reaction then products forms with same configuration

    Simun did you get this

    eduncle-logo-app

    Please ask if you don't get

    eduncle-logo-app

    Simun please respond

    eduncle-logo-app

    yes

    eduncle-logo-app

    Did you get Sni

    eduncle-logo-app

    no I can't

    eduncle-logo-app

    can u simply explain ..when sni occurs condition...catalist ....reagent ...its rate determining steep and its intermediate and questions according to sni

    eduncle-logo-app

    can u ....do this ..pls ?

    eduncle-logo-app

    See this

    eduncle-logo-app

    This is only reaction that Sni I have come through.
