Title: lewis dot structure
Post by: GuRLCrUMbS01 on April 18, 2012, 07:06:58 AM

i get the lewis dot structure but the teacher gave us this and i dont know how to answer this (picture or link below from my tumblr).


WHAT TO DO WITH THE NH2 that is connected to C??

Can you start? How many electrons are in the outer shell of a nitrogen atom? Hydrogen atom? Carbon atom? How many electrons can nitrogen share with hydrogen?

It doesn't matter - those are both perfectly adequate structures.

Later you will learn the three-dimensional geometry of the compounds and the limitations on free rotation of the bonds, and realize that no two-dimensional drawing for this compound could be truly accurate.
