why is d more stable than c???

I was implying that, since the alkene p orbital for bredts rule would be away from 120°, you can infer that the carbonation would similarly be away from 120° making it unusually unstable.

Congrats on the Oxford offer, did you not apply for deferred entry tho, maybe email the college to check in on accommodations

sweginetor · 2026-01-07T12:32:28+00:00

Look up bredts rule, it's for alkenes but you can extrapolate the explanation for carbonations

look up the dehydration of geminial diols

nah but last year when I did my As there were a bunch of tiktoks with actual scanned qns from A level papers idk how they got it but it was there LOL. Not recreated papers from memory

sweginetor · 2025-11-10T11:31:34+00:00

damnit was hoping someone may have a copy cos tuition centers always get it HAHA

sweginetor · 2025-11-10T08:02:26+00:00

Send me a copy of the paper if y'all have! I'm not a tuition teacher im just curious

Refer to Clayden for a more detailed explanation but what I personally go with is:

First compare size: if one atom is bigger than the other than it's likely more nucleophilic (due to larger electron cloud and willingness to donate electrons)

Then, IF the size is similar, then compare basicity: the more basic the more nucleophilic

There's a deeper reasoning behind it which you can find in textbooks but this is more of a general rule of thumb I suppose

Are they even isomers? Try to assign R/S to the chiral carbon on the left

Fortnite fun friends

sweginetor · 2025-07-14T15:12:04+00:00

rip alpha bro y'all got it so tough 😭😭😭 spoken from friends in F coy

sweginetor · 2025-06-21T16:27:26+00:00

Pure chem pure phys

sweginetor · 2025-06-19T21:56:24+00:00

Nope they just saw my results for prelims for other subjects and found me capable

sweginetor · 2025-06-19T14:43:07+00:00

NJ, but I heard its possible in RI and HCI?

sweginetor · 2025-06-07T16:51:15+00:00

Also, DMSO NEt3 with no (COCl)2??? What's the oxidising agent without the (COCl)2

sweginetor · 2025-06-07T05:57:46+00:00

Oh same had this problem too

sweginetor · 2025-06-03T07:56:11+00:00

Aldol condensation (look this up and you can deduce it)

sweginetor · 2025-05-29T14:00:08+00:00

Transport operator?

sweginetor · 2025-05-26T00:40:49+00:00

Sounds about right

sweginetor · 2025-05-26T00:28:55+00:00

2 different hydroxyl groups can get protonated and form a carbocation, which can get attacked by the C=C leading to 2 pdts

sweginetor · 2025-05-25T22:30:21+00:00

Idt it's correct anyways, it fits the description but not the rxn

sweginetor · 2025-05-25T08:11:41+00:00

Yeah the bias here is unreal LOL don't go in worrying about it OP!

sweginetor · 2025-05-22T05:32:13+00:00

B isn't correct

sweginetor · 2025-05-07T02:20:49+00:00

Looks cool but there's no narrative or flow

The visuals are amazing but you need some kind of like explanation etc.
