how can you determine if it's primary, secondary, or tertiary?

[@chase1064]

A Carbon that is bonded to a single Carbon is primary. A Carbon that is bonded to two Carbons is secondary, and a carbon bonded to three is tertiary.

[@frohan007]

@@chase1064 specifically the carbon with the + charge i think

[@parultidkae4924]

it is depended on number of Carbon atoms it's surrounded by, if it is surrounded by 1-C atom, then it's primary, if it's surrounded by 2-C atoms then it's secondary and if it's surrounded by 3-C atoms then it's tertiary. thankyou have a beautiful day

[@AryanJafri-j6t]

9:53 - My professor said the most electronegative atom should have the negative charge as it is more stable, and if I am not wrong Oxygen is more electronegative than Sulfur so why is the negative charge placed on the Sulfur atom.

[@karinacerda3022]

I agree. I’d rather listen to my professor ngl

[@alialgharrawi5033]

It is because sulfur is bigger than oxygen. It is one of the few exceptions.

[@spaceodyssey9788]

When going down ie top to bottom of periodic table we depend on size factor. So here, Sulphur is bigger in size than oxygen and so a negative charge on it would be more stable. (If you go period wise in periodic table ie horizontally then electronegativity is a factor which helps in comparing. )

[@praneethalva7776]

The sulphur atom has vacant d orbitals within which the electron can move freely , thus causing stability of the negative charge over it

[@safa-uc1mk]

3:33 can someone pls explan why 3 tertiary is most stable here ?

[@anthonycoelho6930]

The electron donating R groups (in this case methyls but think of all alkyl groups as electron donating) stabilize the positive charge on the carbon. The greater the substitution, the more stable the carbocation.

[@notrandom6653]

It is because of another effect called hyperconjugation(refer any other videos if you want to know more,its basically a no bond resonance) and hyper conjugation depends on the number of alpha hydrogens,i.e,hydrogen attached to sp³ hybridised carbon near to the charge.More the number of alpha hydrgen more stable the carbocation

[@doctorbigc]

You’ve really helped me with your tutorship.❤❤❤

[@smoky_ved8906]

For those of u who r studying, tertiary carbocation is the most stable carbocation

[@BrianErwin]

9:19 it's because 2s2 is closer to the nucleus than 2p2, and the more s-character, the more stable.. bigger atoms have more s-character

[@aishikiray5627]

hi, i know i'm late, but i really hope you see this. 'bigger atoms have more s-character'- is that because sulphur has 3s subshell while oxygen doesn't?

[@georgiconlon3811]

@9:37 oxygen is more electron neg than sulfur, so wouldn't the major contributor be the structure where the neg charge is on the oxygen, not sulfur...?

[@anikethpai9442]

Electronegativity is the tendency to attract shared pair of electrons to itself. Oxygen is an acceptor, not a contributor.

[@sumitraturi7791]

Sulphur has larges size

[@winterflower4530]

I did a little more research behind this cuz I was thinking the same thing- it turns out that even though oxygen is more electronegative than sulfur, sulfur is much larger due to periodic trends. This large size allows it to spread out the negative charge better making it more STABLE. I think the key is to think which atom is more stable with the negative charge, not which atom is more likely to have the negative charge. In other words, when comparing elements in the SAME COLUMN (like O and S) look at its ability to stabilize the charge rather than just electronegativity - the greater the size of the atom, the more stable it will be with the charge. On the other hand, when looking at elements in the SAME ROW (ex. C vs O) you can just use your electronegativity trends cuz elements in the same row are roughly the same size- hope this helped :)

[@amycool64]

I don’t understand how the positive charges are jumping

[@joharahk4849]

The positive charges are jumping because as shown in the first example, the pi bond is becoming a single bond, basically “losing” a bond, giving it a positive charge since they’re essentially opposite (when a bond is lost it’s positive, when a bond is gained it’s negative). Hope i explained that accurately I'm learning too :)
