Solution Steps

Step 1: Identify the central atoms

The molecule shown has two central atoms: carbon (C) and nitrogen (N).

Step 2: Determine the hybridization of each central atom
  • Carbon (C): The carbon atom is bonded to three atoms (one nitrogen and two hydrogen atoms) and has no lone pairs. This suggests sp² hybridization.
  • Nitrogen (N): The nitrogen atom is bonded to three atoms (one carbon and two hydrogen atoms) and has one lone pair. This suggests sp³ hybridization.
Step 3: Predict the ideal bond angles based on hybridization
  • Carbon (sp² hybridization): The ideal bond angle is approximately 120°.
  • Nitrogen (sp³ hybridization): The ideal bond angle is approximately 109.5°.

Final Answer

  • Carbon: 120°
  • Nitrogen: 109.5°
