Question

the image shows a space satellite and the lewis structure of the monopropellant hydrazine. monopropellants are fuels that are used for spacecraft attitude adjustment and maneuver. hydrazine is an example monopropellant, and its lewis structure is shown in the image. what is the molecular geometry around each of the nitrogen atoms? tetrahedral trigonal planar trigonal pyramidal linear dont test me yet, i am trying to gain an understanding before attempting to answer this question. multiple choice 1 point

Explanation:

In hydrazine ($N_2H_4$), each nitrogen atom has 4 electron - groups around it (3 bonding pairs with hydrogen atoms and 1 lone pair). According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, when an atom has 4 electron - groups around it, the electron - group geometry is tetrahedral. The presence of a lone pair distorts the molecular geometry from tetrahedral to trigonal pyramidal around each nitrogen atom.

Answer:

trigonal pyramidal
