optical isomerism
is this optically active? if yes then how
can we even check optical activity in bondline structure ?...
coordination compounds
not able to understand why (2) is answer and not (3). On calculating CFSE value, according to me, B>A. And H2O is also stronger ligand than F- then why oxidation number on Co is given more importance?
(JEE Main 26th Aug, 2021 PYQ)...
JEE ADV PYQS DOUBT
marks only has 740 PYQs for each subject for advanced is there any other site that gives chp wise PYQ and has more PYQ than Marks?
For JEE 2025 Aspirants...
Doubt to nahi hai par chemical kinetics ke PYQs revise kar raha tha and I realised....
Is question ke liye ye
t₉₉ = 10 ⨯ t₁/₂ = 3 ⨯ t₉₀
t₁/₂ = 120 de rakha tha to
t₉₉ = 1200 ho gaya so ...
Dipole moment doubt
How should I approach these type of questions .. I thought hbr will be more polar than H2S cuz of electronegativity but it isn't the case .. am I missing something?
CFSE
I have read that CFSE order: sq. planar > od>td
but the ans. discussed is 1st option where it is CN=4 is at last...
Resistivity
Which option should be correct for conductors: B or D ?
plz give reason too , from diff channels i saw i got diff. ans....
Area under curve
Is there a way to intuitively know what the smaller part is instead of having to calculate both areas?
