Questions & Step-by-Step Solutions

What is the bond angle in a tetrahedral molecule?
Correct Answer: 109.5 degrees
  • Step 1: Understand that a tetrahedral molecule has a central atom bonded to four other atoms.
  • Step 2: Visualize the shape of a tetrahedron, which looks like a pyramid with a triangular base.
  • Step 3: Recognize that the four bonds spread out as far as possible to minimize repulsion between them.
  • Step 4: Measure the angles between any two bonds; in a tetrahedral shape, these angles are approximately 109.5 degrees.
