25 which of the folowing is most polar (a) (b) () (d)

So it is highly polar

sir, i have problem in how to approach these qs. How to do charge separation by myself and proceed.

I order to make the ring aromatic charge separation occur.

Same is happened in Quasi aromatic compound.

Quasi aromatic compound are also highly polar

Did you get this Sourav

option B structure same case...charge separation is already present and both rings are aromatic

In option A structure both the rings are anti aromatic

got this sourav??

what do you mean by charge separation.. can you explain it with a diagram on the options

see this is charge separation means positive n negative charge

got sourav??

i guess charge separation is done by resonance and if so can we bring positive charge on the small ring and negative charge on big one?

positive charge on big one and negative on small one

sir i guess the small ring has 4 pie electrons?

in case of azulene you are talking about

yes

see here it is done charge separation like this just to know about charge separate but actually it happens like that one of double bond is common to both the rings so that smaller rings gets 6 pi electrons and large ring too get

both become aromatic

sir how to approach this type of. qs? i can't imagine how to separate charges and then think about the structure

practice goc questions and ques by ques the concept you are missing you came to know...then relate this type with aromaticity concept...so overall practice more n more questions of goc

sir is there any material to learn about these concepts of how to deal with charge separation? can you help me out?

wait i'm checking if it available to me...i will put it here you can check it later
