Front

Define hybridization in chemistry.

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals suitable for the pairing of electrons to form chemical bonds.

Front

What is the significance of the VSEPR theory?

Back

The VSEPR (Valence Shell Electron Pair Repulsion) theory is used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell.

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, resulting in a positive and negative end.

Front

What is the difference between a single bond and a multiple bond?

Back

A single bond involves one pair of shared electrons, while a multiple bond (double or triple) involves two or three pairs of shared electrons, respectively.

Front
