Molecular Geometry & Hybridization

Front

What is hybridization in chemistry?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals, which can then form bonds with other atoms.

What is the hybridization and molecular geometry of phosphorus tribromide (PBr3)?

Back

sp³ hybridization with a trigonal pyramidal molecular geometry.

Front

What is the molecular shape of a molecule with sp² hybridization?

Back

Trigonal planar.

Front

Which molecule has an octahedral geometry?

Back

SCl₆ (sulfur hexachloride) has an octahedral geometry.

Front

What type of bonding is characterized by the highest melting and boiling points?

Back

Ionic bonding typically exhibits the greatest melting and boiling points.

Front

Define polar covalent bond.

Back

A polar covalent bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms, leading to a dipole moment.

Front

What is the molecular geometry of a molecule with four bonding pairs and one lone pair?

Back

Trigonal bipyramidal.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have a net dipole moment due to uneven distribution of electrons, while nonpolar molecules have an even distribution of electrons.

Front

What is the shape of a molecule with two bonding pairs and two lone pairs?

Back

Bent or angular.

Front

What is the hybridization of a molecule with a linear shape?

Back

sp hybridization.
