  4. 90 degrees

Questions & Step-by-Step Solutions

What is the bond angle around the carbon atoms in an alkyne?
Correct Answer: 180 degrees
  • Step 1: Understand what an alkyne is. Alkynes are hydrocarbons that contain at least one triple bond between carbon atoms.
  • Step 2: Recognize that the carbon atoms involved in a triple bond are arranged in a straight line.
  • Step 3: Know that when atoms are arranged in a straight line, the angle between the bonds is 180 degrees.
  • Step 4: Conclude that the bond angle around the carbon atoms in an alkyne is approximately 180 degrees due to this linear arrangement.
