Is sodium amide a base?

Sodium amide is an inorganic sodium salt composed of a sodium cation and an azanide anion. It is used as a strong base in organic synthesis. It has a role as a catalyst and a nucleophilic reagent.

Why is sodium amide a base?

NaNH2 is a salt-like material which has a tetrahedral crystal structure. It is composed of sodium ions (Na+) and amide (NH2-) ions, and its chemical structure is shown below. The free amide ions make this molecule a strong base.

Is NaNH2 an acid or base?

strong base
NaNH2 is a strong base, intended to be strong enough to deprotonate the alkyne (pKa ≈ 25). But that would also make it strong enough to deprotonate the alcohol (pKa ≈ 16, close to water), and because the alcohol is a stronger acid, it would be deprotonated first.

Is amide a salt?

Sodium amide, commonly called sodamide (systematic name sodium azanide), is the inorganic compound with the formula NaNH2. It is a salt composed of the sodium cation and the azanide anion.

Is sodium amide ionic or covalent?

A white ionic solid formed by passing dry ammonia over sodium at 300–400°C. The compound reacts with water to give sodium hydroxide and ammonia.

What kind of compound is amide?

amide, any member of either of two classes of nitrogen-containing compounds related to ammonia and amines.

What do you mean by amide?

Definition of amide 1 : an inorganic compound derived from ammonia by replacement of an atom of hydrogen with another element (such as a metal) 2 : any of a class of organic compounds derived from ammonia or an amine by replacement of hydrogen with an acyl group — compare amine, imide.

What elements do amides contain?

An amide is a molecule that has a carbonyl or a carbon double bound to an oxygen attached to a nitrogen group such as NH2.

Are amides acids or bases?

Compared to amines, amides are very weak bases and do not have clearly defined acid–base properties in water. On the other hand, amides are much stronger bases than esters, aldehydes, and ketones.

What are amides examples?

Common examples of amides are acetamide H3C–CONH2, benzamide C6H5–CONH2, and dimethylformamide HCON(–CH3)2. Amides are qualified as primary, secondary, and tertiary according to whether the amine subgroup has the form –NH2, –NHR, or –NRR’, where R and R’ are groups other than hydrogen.
