Step 1: Identify the structure of ClF^3 with minimized formal charges.
The Lewis structure of ClF^3 with minimized formal charges has the central Chlorine atom forming three bonds with Fluorine atoms and having one lone pair of electrons.
Step 2: Analyze the octet rule for the central atom.
The octet rule states that atoms tend to have eight electrons in their valence shell to achieve a stable electronic configuration. In this case, the central Chlorine atom has seven electrons from three bonds and one lone pair, satisfying the octet rule (X is true).
Final Answer
- W: Central atom has an expanded octet (False) - X: The octet rule is obeyed (True) - Y: The central atom has an incomplete octet (False) - Z: The central atom has 2 lone pairs (False)
