Which of the following has different molecular geometry and electron pair geometry?

Explanation

The correct answer is SnCl2. In SnCl2, the molecular geometry is bent due to the presence of a lone pair on the central atom, while the electron pair geometry is trigonal planar. This difference arises because the lone pair occupies space and affects the molecular shape.For SO3, the molecular and electron pair geometries are both trigonal planar as there are no lone pairs on the sulfur atom.In CO2, both molecular and electron pair geometries are linear, as no lone pairs are present to alter the geometry.Finally, BF3 also has the same trigonal planar geometry for both molecular and electron pair structures, as the boron atom does not have lone pairs.
