Molecular Structure & Intermolecular Forces

Front

What is a dipole?

Back

A dipole is a molecule that has a charge distribution where one end is slightly positive and the other end is slightly negative.

Front

In covalent bonds, how are electrons treated?

Back

In covalent bonds, electrons are shared between atoms.

Front

What explains the very high melting and boiling point of water?

Back

The very high melting and boiling point of water is explained by strong hydrogen bonds between water molecules.

Front

How many electrons are used in the Lewis Structure for NO3-?

Back

The Lewis Structure for NO3- uses 24 electrons.

Front

What is electronegativity?

Back

Electronegativity is how good an atom is at attracting electrons.

Front

Define intermolecular forces.

Back

Intermolecular forces are forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions).

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

Explain the concept of hydrogen bonding.

Back

Hydrogen bonding is a type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like oxygen, nitrogen, or fluorine.

Front

What is the significance of molecular geometry?

Back

Molecular geometry determines the shape of a molecule, which influences its reactivity, polarity, phase of matter, color, magnetism, and biological activity.

Front

What are dispersion forces?

Back

Dispersion forces, also known as London dispersion forces, are weak intermolecular forces that arise from temporary dipoles in molecules.
