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
anonymous
  • anonymous
agreed, but how does it bring a change about in the molecule
Photon336
  • Photon336
nice question
Photon336
  • Photon336
@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.
anonymous
  • anonymous
it can have one more extra bond so positive , i suppose
Photon336
  • Photon336
@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|
anonymous
  • anonymous
cl- is nucleophile

  • Photon336
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!

@No.name carbon must always make 4 bonds, there is no exception to this rule.

  • anonymous
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!

  • Photon336
one more thing
anonymous
  • anonymous
yes

  • Photon336
do you know what a carbanion does?
anonymous
  • anonymous
yeah

heterolytic bon cleavage .........

both the lone pairs go to the carbon
Photon336
  • Photon336
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
Photon336
  • Photon336
you mean what i drew right?
anonymous
  • anonymous
oh yes
Photon336
  • Photon336
FYI this would be very hard to do but just to give you an example |dw:1443931658624:dw|
anonymous
  • anonymous
yes got it
anonymous
  • anonymous
just out of curiosity , it might be a lame question can it form a co-oridnate bond with some electrophile
Photon336
  • Photon336
hey @no.name can you show me by drawing that out?
