Question

ammonia is critical to the production of fertilizers. it has been estimated that without the manufacture of fertilizers from ammonia food production would fall so dramatically that the worlds population would decrease by a factor of two! ammonia is one of the most important simple chemicals in the world! what molecular shape does ammonia have, and is it a polar or nonpolar molecule? it is planar and it is nonpolar it is planar and it is polar it is trigonal pyramidal and it is nonpolar it is trigonal pyramidal and it is polar dont test me yet, i am trying to gain an understanding before attempting to answer this question. multiple choice 1 point

Explanation:

Ammonia ($NH_3$) has a central nitrogen atom with three bonding pairs to hydrogen atoms and one lone - pair. According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, the electron - pair geometry is tetrahedral and the molecular shape is trigonal pyramidal. The electronegativity of nitrogen is greater than that of hydrogen, creating polar N - H bonds. The lone - pair on nitrogen also contributes to the overall molecular dipole, making ammonia a polar molecule.

Answer:

it is trigonal pyramidal and it is polar
