E)They are all equal.

Question

Quizplus · Accepted Answer

Quaternary amines have a tetrahedral geometry around the nitrogen atom, which results in bond angles of approximately 109.5 degrees. This is higher than the bond angles in secondary amines and alcohols, which have trigonal pyramidal and bent geometries, respectively. The bond angle in ethers is also approximately 109.5 degrees, but because oxygen is more electronegative than nitrogen and carbon, the C-O-C bond angle is slightly less than the ideal tetrahedral angle.
