Does negative charge means excess of electrons or something or is it formal charges
You mean like this right? for potassium |dw:1443930748032:dw|
in terms of cation/anion(s) ?
@No.name the positive charge is called a carbocation the negative charge on the carbon is called a carbanion
agreed, but how does it bring a change about in the molecule
@no.name please look at this figure tell me what you think |dw:1443930955082:dw|
carbons always make four bonds, so in terms of reactivity, this means that something in this case a nucleophile will attack this.
it can have one more extra bond so positive , i suppose
@No.name look at this. can you tell me which one is the nucleophile which is the electrophile and how this reaction would go? |dw:1443931119460:dw|
cl- is nucleophile
This will help to show you the importance of the carbocation in these types of reactions.
i have not yet started mechanisms , but yeah i get a idea what you are trying to say!
check this out
@No.name carbon must always make 4 bonds, there is no exception to this rule.
nice i get it , yeah i learnt that carbocation and carbanion are reaction intermediates , but needed someone to reinforce it , now the picture is clear thanks buddy!
one more thing
do you know what a carbanion does?
heterolytic bon cleavage .........
both the lone pairs go to the carbon
yep, also there's a charge sitting on the carbon atom, depending on what atoms you have in your molecule this charge will be unstable. see the molecule below. |dw:1443931494309:dw|
i didn't get the figure
you mean what i drew right?
FYI this would be very hard to do but just to give you an example |dw:1443931658624:dw|
yes got it
just out of curiosity , it might be a lame question can it form a co-oridnate bond with some electrophile
hey @no.name can you show me by drawing that out?
