    See When we are asked about solubility we generally take the solvent as water. There is a very famous saying 'like dissolve like'. So in water ionic compound are more soluble but we take solvent as benzene then covalent compound are more soluble

    Sir, I have a question

    eduncle-logo-app

    could you please tell me that pericyclic reactions is an important chapter or not?

    eduncle-logo-app

    How many questions come from this chapter in CUCET ?

    eduncle-logo-app

    sir please reply ๐Ÿ™

    Smaller theย cation, greater is itsย polarising power. Larger theย chargeย on theย cation, greater is itsย polarising power. Henceย covalent characterย increases . Greater theย chargeย on the anion, more easily it getsย polarisedย ...

    eduncle-logo-app

    more the covalent character,lesser is the solubility

    eduncle-logo-app

    got meghna??

    eduncle-logo-app

    if you have any doubt meghna then please ask and accept the answer if you got it๐Ÿ™๐Ÿ™

    eduncle-logo-app

    sir what is the difference between polarization and polarising power?Are they same or different

    eduncle-logo-app

    polarising power is used for cationic species...so that it deform the electron cloud of anionic species

    eduncle-logo-app

    polarisation is just a concept in which polarising power is there for cation and polarisibilty is there for anion

    eduncle-logo-app

    thank you sir

    eduncle-logo-app

    I got it

    eduncle-logo-app

    welcome meghna๐Ÿ˜Š๐Ÿ‘

    eduncle-logo-app

    Sir I have a question

    eduncle-logo-app

    yes meghna ask

    eduncle-logo-app

    How many questions come from Pericyclic reactions in CUCET?

    eduncle-logo-app

    is this topic important??

    eduncle-logo-app

    I think this chapter is not included in iit jam syllabus

    eduncle-logo-app

    sir please reply ๐Ÿ™

    eduncle-logo-app

    meghna...pericyclic is there in jam syllabus...diels alder,electrocyclic sigmatropic part

    eduncle-logo-app

    for cucet there are basic questions asked...organic part ques level is good

    eduncle-logo-app

    could you please tell me some selected topics which come in CUCET

    eduncle-logo-app

    first read meghna basics part like goc first...and practice all questions of goc..then it gives u basic idea and also you gain interest in learning organic chem

    eduncle-logo-app

    for CUCET meghna??

    eduncle-logo-app

    yes sir

    eduncle-logo-app

    in 2021 you will give entrance na??

    eduncle-logo-app

    25.ques asked from org part...i have seen previous year ques...organic part level was good...10 ques u can do directly...for 15 ques...mainly ques asked from goc part reaction mechanism and named reaction part

    eduncle-logo-app

    for your convenience , i will analyse previous year questions and topic wise i will put it here...u can see tomorrow...

    eduncle-logo-app

    Thank you very much sir ๐Ÿ™๐Ÿ™๐Ÿ™

    eduncle-logo-app

    welcome meghna and study n practice org quest.๐Ÿ‘

    eduncle-logo-app

    Sir I have CUCET question papers of last 4years .

    eduncle-logo-app

    If you want then I can send you

    eduncle-logo-app

    i too have...i will analyse all these and send it to u๐Ÿ˜Š

    eduncle-logo-app

    ok sir

    eduncle-logo-app

    ya sure...

    eduncle-logo-app

    Thank you very much sir ๐Ÿ™

    eduncle-logo-app

    Read this part first and practice all the questions on these parts...It surely helps๐Ÿ‘

    eduncle-logo-app

    https://drive.google.com/file/d/1CgsH_sK0gBDv11g3MwH-DKfkOBWYhZ_j/view?usp=drivesdk for name reactions and reagent part read this๐Ÿ˜Š

    eduncle-logo-app

    welcome...study and practice more and more.....u will surely achieve success๐Ÿ‘

    eduncle-logo-app

    sir the link you sent for name reaction and reagents didn't open and shows that unable to access the document

    eduncle-logo-app

    okk wait

    eduncle-logo-app

    https://drive.google.com/file/d/1O4HVrCG7ulcQ-D9dVSGpQY3UBTlA6oFC/view?usp=drivesdk now check it

    eduncle-logo-app

    sir, again it shows unable to access the document

    eduncle-logo-app

    repeat 2 to 3 times...sometime drive opening may cause error

    eduncle-logo-app

    ok sir I am trying

    eduncle-logo-app

    sir, repeatedly it shows unable to access

    eduncle-logo-app

    ok sir I will manage

    eduncle-logo-app

    sir I can find it from other books

    eduncle-logo-app

    Thank you sir for helping me

    eduncle-logo-app

    sorry for inconvenience..but it is opening in my drive....๐Ÿ˜Š

    eduncle-logo-app

    Thank you very much for always helping me

    eduncle-logo-app

    always welcome๐Ÿ˜Š

    More the charge density, more will be the polarizing power, more will be the covalency. Hence lesser will be the solubility.

    eduncle-logo-app

    See When we are asked about solubility we generally take the solvent as water. There is a very famous saying 'like dissolve like'. So in water ionic compound are more soluble but we take solvent as benzene then covalent compound are more soluble

    eduncle-logo-app

    So Do the Solubility question accordingly.

    eduncle-logo-app

    ok sir

    eduncle-logo-app

    thank you
