Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

check it Simun
follow the rule which I've swnt
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
sir here 4 covelent bond na
how can 6
check CH2 bonds also actually 2 bonds come from CH2
got it??
ohhh yes sir but sir in st iii - charge on c is least stable na
yes, yee
so why iii greater then ii
ohh I got it N cant be pentavelent
in st iii N is pentavelent
sir can u clearly compare between structure ii and st iii
yes
got it??
so why the ans is I>iii> ii >iv
if ii > iii so why in Ans iii> ii
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
unlike charge must be nearer to each other sir
yes
but sir given ans B is correct in the booklate
according to it
yes, I've solved it ans B
Don't be confused. again try to understand
here i say that iv is least stable due to least covalent bonds
yes sir
then ww will check charge separation so according to it like charge must be near so ii is less stable than i,ii
ok sir I understand
πππππ
Simun i always try to simplify method so you can easily understand. and also provide supporting concept
Now according to this flow chart you will be able to solve any questions related to stability of RS
yes sir ur concepts are so understandable ....I m glade that u teach me ππ
πππ
so sir according to this first check likecharge closer then electronegativity concepts? m I right sir
yes
now try to solve another question
ok sir
try this question
after solving sent it on this app
ok sir sure
