@GaurangTandon What is the driving force for the second reaction? Why does it happen?
 
Gaurang Tandon
Gaurang Tandon
these are free radicals; the alkoxyl radical could combine with another alkoxyl radical; or it could react with HBr
I guess which molecule it combines with is random
and the driving force is probably completing its own octet (and the expense of another's)
though I truly don't know the extra details that you're probably looking for :/
@Abcd ^^^^

@GaurangTandon what allows that? Why does Br not protest against its octet loss
 
Gaurang Tandon
Gaurang Tandon
i totally don't know
:/

@GaurangTandon can I ask on main
Hi @MollyCooL, do you go to FIITJEE too? Did you appear for the RSTs?
@MollyCooL Please see my latest question above.
@MollyCooL Are you a girl or a boy? Just asking...
 
MollyCooL
MollyCooL
Yes I do. (CRP from class 11). RSTs?

@MollyCooL Reshuffling tests

Boy 😂
They dont happen much in CRP.

@MollyCooL I am in CRP too, its happening for all.

Not here tho. Where you from?

Okay. Checking qn. Disclaimer: im poor in org they have just started goc for us
What do you think drives free radical halogenation? I would say its the same here too

@Abcd i'm totally not sure if it's a noob question or a truly deep one
 
MollyCooL
MollyCooL
Lol
Shouldnt it be because they are free radicals?
@GaurangTandon
Also why not 2-Ethoxy? First letter to be capitalised right?
Any1? 👀

ha i'd just left
and am gonna leave now, just dropping by to say that
@MollyCooL first letter is capitalized when it begins the sentence
not in the middle of it
ok bye! also I like your emojis, they're cute and funny!

@Abcd The driving force for the second reaction, as estimated correctly earlier, is the completion of the octet at the expense of another's.
Oxygen is in the IInd period and it is not happy when there is a vacancy in its outermost shell, i.e. the L shell, i.e. the 2nd shell.
Bromine, on the other hand, is in the IVth peiod. It is much more tolerant towards a vacancy (far away) in the N shell.

@EashaanGodbole hmm good point! :D

If you want the comparison between energies of forming O and Br radicals, just see the BDE (bond dissociation energies), which are recorded for homolytic fission (what we are looking at here).

@EashaanGodbole Why is bromine more tolerant to vacancy?
Its not obvious to me

@GaurangTandon I was talking about IUPAC nomenclature

@Abcd The pull of the nucleus is not as strong at that distance and with all the shielding.

Conjecture:
Water is more basic than $\ce{X-}$, $\ce{X}$ being a halogen

Sources: A reaction
Is my conjecture correct? Could anyone verify it?
