Chemistry Assignment: Molecular Structures, Bonding, and Properties

This chemistry assignment provides solutions to problems involving molecular structures, Lewis diagrams, and electron-pair geometry. It covers topics such as the identification of intermolecular forces, including dipole forces, induced dipole forces, and hydrogen bonding, within various chemical compounds. The assignment also includes questions on classifying organic compounds as alkanes, alkenes, alkynes, or aromatic compounds, along with their saturation levels. Furthermore, it addresses the naming of chemical compounds based on their formulas, such as Barium chloride, Magnesium oxide, and others. Finally, the assignment involves the analysis of cycloalkane structures and the identification of molecules with the same molecular formula. This assignment offers a comprehensive review of fundamental chemistry concepts.

The Lewis diagram for PCI3 is
The electron-pair geometry around the P atom in PCI3 is 3 electronic pair
There is, are 3 lone pass) around the central atom, so the geometry of PCI3 is Trigonal pyramidal
The Lewis is diagram for GeH4 is:
The electron-pair geometry, around the Ge atom in GeH4 is Four electronic pair.
There is.'''are 2 lone pair(s) around the central atom, so the geometry of GeH4 is tetrahedral
