Attack of amines on aldehydes and ketones (2)

[baydoun1991]

i hate the asterisk idea, because it just adds more rubbish to the atom! i wish you havent used it.

why do gringuard reactions stop at category 1 reactions?

why does the O not leave and a second gringuard attack?

[guzzbar]

nevermind... :)

y is there a negative sign on the oxygen at 3:10 if it is attached to the carbonyl carbon and a hydrogen? thanks

[mh43460]

@guzzbar actually it is oxygen bonded to C and H

its neutral

in next step at ,where it gives its pair of electon to H+ it becomes +ve 3:47

Isn't use if equilibrium arrows dependent on pKa's and ease of reversibility of each reaction?...
