1,Is CH3NH2 have two central atoms? C and N? C is the least electronegative, so I thought that only C is central atom
2. Explain why only the lone pairs on the central atom are taken into consideration when predicting molecular shape. What substances from the lab activity have more than one central atom?
my answer is when we predict the molecular geometry shape based on the VSEPR theory.the presence of loan pairs around the central atom affects the arrangement of the other atoms, and dictates the shape of the entire module.
for example .co2 and h2o are Bothe bonded 3atoms. the difference is the central atom of o has 2 loan pairs. so it effects the shape to be bent. h2o2,c2h4,ch3nh2 have two central atoms
