Question

which structure has the central atom placed correctly?
c cl cl o
cl
o c
cl
o
cl c cl
c
cl cl o
c
cl o cl

Explanation:

In a molecule, the central atom is usually the least electronegative atom (except for hydrogen). Among \(C\), \(Cl\), and \(O\), carbon (\(C\)) is less electronegative than \(O\) and \(Cl\). In the structure \(O\) \(Cl\) \(C\) \(Cl\) (the second - option structure), carbon is in the central position, which is correct as per the rule of central - atom placement (least electronegative atom in the center, and also considering that carbon can form multiple bonds to accommodate the other atoms in a stable molecular structure).

Answer:

The second - option structure (with \(C\) in the central position among \(O\), \(Cl\), \(C\), \(Cl\)) has the central atom placed correctly.
