What would be the spatial arrangement (shape)of the atoms of the methyl anion,:CH₃^-?

Question

Quizplus · Accepted Answer

The methyl anion has four regions of electron density around the central carbon atom, including three covalent bonds to hydrogen (H) and one lone pair of electrons. This suggests a trigonal pyramidal shape, where the three H atoms are arranged in a plane and the lone pair occupies the fourth position, causing the bond angle to deviate slightly from 109.5 degrees in a symmetrical tetrahedral shape. Therefore, the best choice is E, trigonal pyramidal.
