Title: organic reaction mechanism problem?
Post by: sidharth on February 12, 2010, 11:36:06 AM

I have a simple elimentary reaction but dont know why the the c with lonepair attacked the carbon and not the +vely charged nitrogen?
M y second reaction how am I supposed to know the reaction site how do I know where will It attack?

First reaction : What happens when N is attacked? Look at the product. Is it stable?

Second reaction : Which site do you think is the most vulnerable to be attacked by a nucleophile? (OH^- in this case) And why?
