Multiple Choice

Which of the following statements correctly describes the Lewis dot structure of the neutral compound Cl2O2?

Each chlorine atom is bonded to one oxygen atom, and the two oxygen atoms are connected by a double bond.

Each chlorine atom is bonded to one oxygen atom, and the two oxygen atoms are connected by a single bond.

The two chlorine atoms are bonded to both oxygen atoms, forming a four-membered ring.

Both chlorine atoms are bonded directly to each other, with each also bonded to an oxygen atom.

Verified step by step guidance

Step 1: Determine the total number of valence electrons available for the molecule Cl2O2. Chlorine (Cl) has 7 valence electrons, and oxygen (O) has 6 valence electrons. Calculate the total by adding the valence electrons from 2 chlorine atoms and 2 oxygen atoms: $2 \times 7 + 2 \times 6$.

Step 2: Consider the connectivity of atoms based on typical bonding patterns and electronegativity. Oxygen often forms two bonds, and chlorine typically forms one bond in such compounds. Use this to hypothesize possible bonding arrangements between Cl and O atoms.

Step 3: Draw possible Lewis structures that satisfy the octet rule for each atom, ensuring that the total number of electrons used in bonds and lone pairs equals the total valence electrons calculated in Step 1.

Step 4: Evaluate each proposed structure for formal charges to identify the most stable Lewis structure. The best Lewis structure usually has formal charges closest to zero on all atoms.

Step 5: Compare the candidate structures to the given options, focusing on the bonding between chlorine and oxygen atoms and the bond order between the two oxygen atoms (single or double bond) to select the correct description.
