Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Understand the Molecular Structure
N₂H₄ (hydrazine) has two nitrogen atoms connected to each other, with hydrogen atoms attached to each nitrogen. To determine the molecular geometry, we need to examine the electron configuration and bonding around each nitrogen atom.
Step 3:: Draw the Lewis Structure
\bullet 1 \text{ electron from the N-N single bond}
- Each nitrogen atom will have:
Step 4:: Determine Electron Pair Geometry
- Each nitrogen atom will have 4 electron pairs (2 bonding, 2 non-bonding) - This suggests a tetrahedral electron pair geometry according to VSEPR theory
Step 5:: Analyze Molecular Geometry
- With 2 bonding pairs and 2 non-bonding (lone) pairs - The molecular geometry around each nitrogen is pyramidal - Bond angle will be slightly less than 109.5° due to lone pair repulsion
Final Answer
Key Characteristics: - Tetrahedral electron pair geometry - Pyramidal molecular geometry - Approximate bond angle less than 109.5°
