Front

What is a double bond in chemistry?

Back

A double bond is a type of chemical bond where two pairs of electrons are shared between two atoms, resulting in a total of four shared electrons.

Front

How many lone pairs of electrons does carbon (C) typically have?

Back

Carbon typically has no lone pairs of electrons in its most common bonding scenarios.

Front

What is O2 classified as?

Back

O2 is classified as a diatomic molecule, which means it consists of two atoms of the same element.

Front

What is the molecular shape of a molecule with two bonding pairs and no lone pairs?

Back

The molecular shape is called Linear.

Front

What is the molecular shape of a molecule with three bonding pairs and no lone pairs?

Back

The molecular shape is called Trigonal Planar.

Front

Define a diatomic molecule.

Back

A diatomic molecule is a molecule that consists of two atoms, which can be of the same or different elements.

Front

What is the significance of lone pairs in molecular geometry?

Back

Lone pairs can affect the shape of a molecule by repelling bonding pairs, leading to different molecular geometries.

Front

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

Back

A single bond involves one pair of shared electrons, while a double bond involves two pairs of shared electrons.

Front

What is the VSEPR theory?

Back

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

Front

What is the molecular shape of a molecule with one central atom bonded to three other atoms and one lone pair?

Back

The molecular shape is called Trigonal Pyramidal.
