HYBRIDISATION POP FLASHCARD

Front

What is hybridization?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals that can accommodate the bonding of atoms in molecules.

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the significance of sigma bonds in molecular structure?

Back

Sigma bonds are the strongest type of covalent bond due to the large overlap area of orbitals.

Front

What type of hybridization does a carbon atom undergo when it forms a double bond?

Back

sp² hybridization.

Front

How many sigma and pi bonds are present in a double bond?

Back

A double bond consists of 1 sigma bond and 1 pi bond.

Front

What is the geometry of a molecule with sp hybridization?

Back

Linear geometry with a bond angle of 180°.

Front

What is the geometry of a molecule with sp² hybridization?

Back

Trigonal planar geometry with a bond angle of 120°.

Front

What is the geometry of a molecule with sp³ hybridization?

Back

Tetrahedral geometry with a bond angle of 109.5°.

Front

What determines the polarity of a molecule?

Back

The polarity of a molecule is determined by the difference in electronegativity between the bonded atoms and the molecular geometry.

Front

What is the role of lone pairs in VSEPR theory?

Back

Lone pairs repel more strongly than bonding pairs, affecting the molecular geometry.
