If the symbol x represents a central atom, y represents outer atoms, and z represents lone pairs on the central atom, the structure (2 lone pairs around x) could be abbreviated as xy2z2. classify these structures according to their shape. molecular geometries: linearbent 120bent 109trigonal pyramidalt-shapedsee sawsquare planarsquare pyramidalpossiblities: xy4z2xy5zxy2zxy2z3xy4zxy2z2xy3z2xy3 z

Explanation:

According to the VESPR theory, the molecular geometry depends on the repulsion of the pairs of electrons of the valence shell.

Let

X: central atomY: outer atomZ: lone pair

Classify these structures according to their shape.

XY₄Z₂: This molecule has 4 + 2 = 6 electron domains so the corresponding electron geometry is octahedral. Given there are only 4 outer atoms, the molecular geometry is square planar.XY₅Z: This molecule has 5 + 1 = 6 electron domains so the corresponding electron geometry is octahedral. Given there are only 5 outer atoms, the molecular geometry is square pyramidal.XY₂Z: This molecule has 2 + 1 = 3 electron domains so the corresponding electron geometry is trigonal planar. Given there are only 2 outer atoms, the molecular geometry is bent 120.XY₂Z₃: This molecule has 2 + 3 = 5 electron domains so the corresponding electron geometry is trigonal bipyramidal. Given there are only 2 outer atoms, the molecular geometry is linear.XY₄Z: This molecule has 4 + 1 = 5 electron domains so the corresponding electron geometry is trigonal bipyramidal. Given there are only 4 outer atoms, the molecular geometry is seesaw.XY₂Z₂: This molecule has 2 + 2 = 4 electron domains so the corresponding electron geometry is tetrahedral. Given there are only 2 outer atoms, the molecular geometry is bent 109.XY₃Z₂: This molecule has 3 + 2 = 5 electron domains so the corresponding electron geometry is trigonal bipyramidal. Given there are only 3 outer atoms, the molecular geometry is T-shaped.XY₃Z: This molecule has 3 + 1 = 4 electron domains so the corresponding electron geometry is tetrahedral. Given there are only 3 outer atoms, the molecular geometry is trigonal pyramidal.

Ithink its solid. hope this
