Since jee mains is over and i am pretty confident in it , i am starting with jee advanced preparation. What are you guys planning?
are you not going to study for boards ?
Board + adv
Time devision as in boards -80% and adv -20%
You can do 50% boards and 50% advanced since pcm is kinda done for mains. This is what i am doing.
i am like
60%boards 30 % mains 10%advanced
bro i didnt study my optional subjects once for this year so need to do it. i opted electronics which is too much ratta based but like half physics
They will tell the details in a paragraph if they give. Explicitly not mentioned in syllabus
But learn nacl, cscl, zns, graphite, fluorite, Antifluorite, spinel, inverse spinel
What about identification of spinels/inverse spinels? @Rudra_d
I haven’t studied spinels.
General formula AB2O4 … O 2- is ccp , 1/8th TV is occupied by A2+ and 1/2th of OV is occupied by B 3+
Eg. MgAl2O4, ZnFe2O4
Inverse spinel Fe3O4 ( FeO. Fe2O3 )
Fe3+:Fe2+ = 2:1 … Fe2+ and half of Fe3+ occupy OV and the other half of Fe3+ occupy TV
Haan bro this is all dandy, but how do we identify wether a particular compound is a spinel or an inverse spinel? @Aswin24
Edited after translation @Aswin24
I have seen a few problems only in this part… They mostly can be solved by remembering the general formula of Spinel cpds… Not much type here bro @Ishaan_Shrivastava
Another thing Idk Hindi ( only to some extent )
Wired ! Hearing this for first time
in spinel if A2+ CFSE is higher then inverse
if B3+ CFSE is higher then normal

bro, The circular polarized EM waves as the name suggest a component of it, describes a circular path… The rotating vector is the Electric field vector of constant magnitude…
( Ig polarization is not in JEEA syllabus )
For the second one, that’s an important point bro, surface has two interfaces , one at bottom and other at top ( You shouldn’t forget this any time ) but a water droplet has only one interface ( if you can imagine )… As there are two interface ( separated by a small thickness ) always these typ of ST sums involve that factor 2…
@Rachit_Gandhi Be careful in questions where do you need to use that factor 2 or not based on the questions scenario
i thought it was for soap films thanks a lot bro
