    follow the rule which I've swnt

    eduncle-logo-app

    here all the resonating structures are ionic so we will check the covalent bonds. str. iv have least number of covalent bonds so least stable

    eduncle-logo-app

    sir here 4 covelent bond na

    eduncle-logo-app

    how can 6

    eduncle-logo-app

    check CH2 bonds also actually 2 bonds come from CH2

    eduncle-logo-app

    got it??

    eduncle-logo-app

    ohhh yes sir but sir in st iii - charge on c is least stable na

    eduncle-logo-app

    yes, yee

    eduncle-logo-app

    so why iii greater then ii

    eduncle-logo-app

    ohh I got it N cant be pentavelent

    eduncle-logo-app

    in st iii N is pentavelent

    eduncle-logo-app

    sir can u clearly compare between structure ii and st iii

    eduncle-logo-app

    yes

    eduncle-logo-app

    got it??

    eduncle-logo-app

    so why the ans is I>iii> ii >iv

    eduncle-logo-app

    if ii > iii so why in Ans iii> ii

    eduncle-logo-app

    sorry... i make mistake according to rule. first we will check like charge. like charge must be near to each other so according to this i and iii is more stable than ii

    eduncle-logo-app

    unlike charge must be nearer to each other sir

    eduncle-logo-app

    yes

    eduncle-logo-app

    but sir given ans B is correct in the booklate

    eduncle-logo-app

    according to it

    eduncle-logo-app

    yes, I've solved it ans B

    eduncle-logo-app

    Don't be confused. again try to understand

    eduncle-logo-app

    here i say that iv is least stable due to least covalent bonds

    eduncle-logo-app

    yes sir

    eduncle-logo-app

    then ww will check charge separation so according to it like charge must be near so ii is less stable than i,ii

    eduncle-logo-app

    ok sir I understand

    eduncle-logo-app

    πŸ‘πŸ‘πŸ˜ŠπŸ˜ŠπŸ˜Š

    eduncle-logo-app

    Simun i always try to simplify method so you can easily understand. and also provide supporting concept

    eduncle-logo-app

    Now according to this flow chart you will be able to solve any questions related to stability of RS

    eduncle-logo-app

    yes sir ur concepts are so understandable ....I m glade that u teach me πŸ™πŸ™

    eduncle-logo-app

    πŸ˜ŠπŸ˜ŠπŸ™

    eduncle-logo-app

    so sir according to this first check likecharge closer then electronegativity concepts? m I right sir

    eduncle-logo-app

    yes

    eduncle-logo-app

    now try to solve another question

    eduncle-logo-app

    ok sir

    eduncle-logo-app

    try this question

    eduncle-logo-app

    after solving sent it on this app

    eduncle-logo-app

    ok sir sure

    eduncle-logo-app

    you are right Simun

    eduncle-logo-app

    Option B is correct
