What is London forces and dipole-dipole?

What is London forces and dipole-dipole?

The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction.

What type of molecules have dipole-dipole forces?

Dipole-dipole forces occur between molecules with permanent dipoles (i.e., polar molecules). For molecules of similar size and mass, the strength of these forces increases with increasing polarity. Polar molecules can also induce dipoles in nonpolar molecules, resulting in dipole-induced dipole forces.

What holds atoms together in a solid?

The bonds that hold atoms together to form molecules are called covalent bonds. They are pretty tough and not easily made or broken apart. But there is more to bonds between atoms than just energy—they are also what gives a molecule its shape. …

What is a solid 2nd grade?

There are three phases of matter that are studied in second grade: solids, liquids, and gases. Solids keep their shape and have a definite volume. Liquids have a definite volume (1 gallon of water in a bucket is still one gallon if poured into a sink) and it takes the shape of its container.

What are the four types of solid?

There are 4 major types of solid: molecular, covalent network, ionic, and metallic.

What type of solid is NaOH?

Sodium hydroxide (NaOH) is a corrosive white crystalline solid that readily absorbs moisture until it dissolves. Commonly called caustic soda, or lye, sodium hydroxide is the most widely used industrial alkali. It is highly corrosive to animal and vegetable tissue.

What is soluble in NaOH?


Is NaOH a solid?

At room temperature, sodium hydroxide is a white, odorless solid. Liquid sodium hydroxide is colorless and has no odor. It can react violently with strong acids and with water. Sodium hydroxide is corrosive.

What is the chemical formula for sodium hydroxide?


How basic is NaOH?

Differentiating acids from bases is easy. Everyone knows that sodium hydroxide, NaOH, is a base. If a compound that contains an OH group also contains a metal ion, then it is a base. Besides NaOH other examples are LiOH, KOH, Mg(OH)2, and Ca(OH)2.
