Nucleophiles ....Moved from general chem board
« on: November 04, 2005, 09:59:37 AM »
Water makes a fairly poor nucleophile.
but why?

is it because of it's size? or are there other factors as well?
does polarity come in to play here aswell?

any input guys would be fabulous!

I just thought - since they're nucleophiles - they deserve to be on the organic chem board. lol
sorry if I'm stepping on anyone's toes...

Generally, fully charged molecules will be better nucleophiles that uncharged molecules like water.  You also have to contend with the energetics of placing a positive charge on an electronegative atom following the attack.
