size and polarizable effects are contracdictory,if size of the atom is larger more polarizablity is increases, therefore larger the size nucleophilicity increases. for (CH3)3C- > (CH3)2N->CH3O-
and also C->N->O->F- C size is larger than N,O and F.
I->Br->Cl->F- I- is larger in size than Br-, Cl- and F-

Hi,
I am quite confused I ampretty sure in an SN2reaction I- would be a good electrophile not nucelophile?

[…] you like to learn about the nucleophiles that will attack these electrophiles? Please go to strong nucleophiles to get a good flavor of […]

In reply to Haashir. Aqueous NaOH protonates OH group to make it a good leaving group, H2O. Than iodide is able to replace OH group.

If the iodide ion is a stronger nucleophile than the hydroxide ion, why does the latter displace the former in a reaction involving aqueous Sodium hydroxide and alkyl iodide?

In reply to felix. Sn1 proceed faster in more polar solvent compare to Sn2. if i not mistaken.

So, would R-O-NH2 be a fair nucleophile or a weak nucleophile? I’m thinking it would be weaker than NH3 because of the oxygen, but I’m not sure.

Thank you so much for this!!!!!
