Want to see this answer and more? Of course, it is the configuration of atoms (not electrons) that defines the the shape of a molecule, and in this sense ammonia is said to be pyramidal (not tetrahedral). Thus, the angle between 2 bonds in OI2 is actually less than 109.5 degrees. It is because in case of O F 2 electrons are nearer to fluorine due to high electronegativity of F compared to C l to B r and because of this repulsion between electron decreases; so as bond angle. It is close to the tetrahedral angle which is 109.5 degrees. The measured bond angles of these compounds (H 2 O 104.5º & NH 3 107.3º) show that they are closer to being tetrahedral than trigonal or linear.
