expansion
just express the lost volume using the density at 100c cuzthat’s when overflow happens.

expansion
okay so you're basically right, but you dont need the density at 0C explicitly

why cant d0 be sq planar ??
Tetrahedral or octahedral makes more sense cuz ligands are better spaced out thusreducing repulsion.

why cant d0 be sq planar ??
d0 metals don’t go square planar because there’s no d-electron to stabilize that shape. In sq planar the highest-energy orbital ie dx2-y2 s left completely empty.....so there’s no gain.

reimer tiemann
yep cuz reimer tiemann rxn is ortho slective. plus higher e density near O- of ortho due to strong I- and R+ can be one reason too ig

Friedel craft rxn.
and for phenol, oh grp does hbonding and also interacts with alcl3. plus its already reactive enough for eas toh side rxn dominates

Friedel craft rxn.
aniline main lp coordinats with alcl3 which deactivates the ring instead of making it more reactive.

aniline and phenol dono main there is sm interaction with alcl3 which makes the catalyst less reactve.

and won't it be independent of temp..like it doesn't change ea itself just the fraction of molecules that have enough energy to react.

Chemical kinetics, factors affecting activation energy
i think surface area one is thoda galat....like it doesnt directly affect ea but if the medium is let's say sold and gas ya solid and liq then a larger surface area exposes more ractive sites which can indirectly influence how rxn proceeds.
