I have a dbt i was deriving result and got that Delta T=lemda g delta H only when theta2=±theta1
I think this is possible only when delta H=0 which doesn't make the result sensible...

Ionic Mobility
This is a jee mains pyq but I don't understand the reasoning given if it's even true or not, the answer given is 1

Resonance
Our teacher thought us concept of counter resonance that it is very unstable (its resonance when 2 different electron density region trying to get stabalised from same pi bond of vacant orbital or something so they counter each other and thats very unstable)
But then HNO3 has equivalent resonance but NO3- also has counter resonance so is not HNO3 should have higher resonance energy
Also one more dbt why does HNO3 dont have intra H bond...
work by real gas
wrote P in terms of V from real gas eqn then W = Pdv integral
everything figured out but what should be unit of "a" ? should i convert to m^4...

Coordinate by vectors
Prove reflection property of parabola by vectors (like in optics we find reflected light vector) i got confused btw someone think it once
Organic Resonance Doubt
Which one is more stable and why?
My reasoning is is ch3 is bulky hence the o is more electron negative and would be more withdrawing the electrons from the benzene ring...

parabola
The co-ordinates of focus of a parabola which touches x = 0, y = 0, x + y = 1 and y = x - 2 are
a)3/5,9/5 b)6/5,2/5 c) 1/3,1 d)2/5,1...
rotation
for part a) why cant we just say it would be sqrt(4g/l) as we derived in wpe that min vel to complete a circle for a rod is sqrt(4gl)
