6 Questions
What is the primary factor that determines the shape of a molecule, according to the Electron Pair Repulsion Theory?
Electron pairs arrange themselves around a central atom to be as far apart as geometrically possible.
What is the order of strength of repulsion between electron pairs in a molecule?
Lone pair-lone pair > Lone pair-bond pair > Bond pair-bond pair
What is the term for a molecule that has separated centres of charge?
Dipole
How many atoms are typically present in a molecule with a trigonal planar shape?
4 atoms
What is the difference between a dipole and a polar molecule?
A dipole refers to a separated center of charge, while a polar molecule is a molecule with a permanent electric dipole moment.
Why can a molecule with polar bonds still be non-polar overall?
A molecule with polar bonds can still be non-polar overall if the dipoles are symmetrically arranged, resulting in a cancellation of the dipole moments.
Learn about the different shapes of molecules, including linear, V-shaped, and trigonal planar, and how electron pairs arrange themselves around a central atom according to the Electron Pair Repulsion Theory. Understand the concept of polar bonds and non-polar molecules.
