Questions and Answers

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 Signup and view all the answers

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. Signup and view all the answers

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. Signup and view all the answers
