A display shows a model with two carbons joined by one single bond. Each carbon is also bonded to two H atoms and one Cl atom. Look along the C–C bond. In the model the rear carbon can rotate around this bond while keeping all its attachments.
Question 1
Which observation supports that the two views have the same connection map?
- The two C–Cl arrows are opposite in both views.
- Each Cl remains attached to the same carbon.
- The back arrow has the same direction in both views.
- Both views show a broken C–C bond.
Question 2
Describe the difference between the two views that cannot be seen from the shared molecular formula.

The display compares only the two equal-length C–Cl dipole arrows projected into this view. Their projected contributions cancel if the arrows point in exactly opposite directions.
Question 3
Use the model to determine which view gives cancellation for these two arrows.

Question 4
Sketch the two C–Cl arrows in a new view with the front arrow up and the rear arrow 60° to the left of upward. Label front and rear.
