Questions & Step-by-Step Solutions

What is the bond angle in a trigonal planar molecule?
  • Step 1: Understand what a trigonal planar molecule is. It has three atoms bonded to a central atom.
  • Step 2: Visualize the shape of a trigonal planar molecule. It looks like a flat triangle.
  • Step 3: Recognize that the three atoms are evenly spaced around the central atom.
  • Step 4: Since the three atoms form a triangle, the angles between them are equal.
  • Step 5: Calculate the bond angles. In a triangle, the total angle is 360 degrees, and there are three angles, so each angle is 360 degrees divided by 3.
  • Step 6: Therefore, each bond angle in a trigonal planar molecule is 120 degrees.
