Sally. What causes CH3- to have exactly the same bond angles for a tetrahedral structure instead of having slightly less angles? Write balanced chemical equations for all transferals of the compounds from organic to aqueous phases and for all precipitation reactions. Vous pouvez modifier vos choix à tout moment dans vos paramètres de vie privée. Hint: Two out of three carbons are in sp 2 hybridized state. Because the lone pair's electron are more diffuse, this causes the bond angles of these two molecules to be a bit less than 109.5 degrees, instead of exactly 109.5. This compound is drawn like so, with the "CNH" atoms highlighted: This is called dimethylamine; amine, because of the "NH", and dimethyl because of the two "CH"_3 groups on the nitrogen. Identify the number of hydrogen atoms bound to each carbon in the structure. Krista 3L Posts: 10 Joined: Fri Sep 26, 2014 9:02 pm. CH3OCH3 2.
