is kcn molecular or ionic?

Covalent and ionic bond and ionic exists between the atom KCN molecules with a large electronegative difference. Ionic bonds hold together K+ and CN- ions. But covalent bond is present between Nitrogen and Carbon atoms in CN-ions. Thus, both covalent and ionic bond and ionic is existsing between KCN molecules.

Answer and Explanation: KNO3 is a strong electrolyte. This means that the compound will break apart into K+ and NO3 - ions in solution.

The resulting solution will be alkaline because KCN is a salt of a strong base and weak acid. It undergoes anionic hydrolysis when dissolved in water.

Ionic bonds form when atoms transfer electrons between each other, forming ions that are electrically attracted to each other forming a bond between them. Sodium chloride (NaCl) is a typical ionic compound. The picture below shows both a sodium and a chlorine ion.

An ionic compound is made of a metal element and a nonmetal element. In potassium chloride, the metal element is potassium (K) and the nonmetal element is chlorine (Cl), so we can say that KCl is an ionic compound.

When the two atoms are in contact, potassium readily transfers its outer electron to chlorine which readily accepts it, resulting in both atoms achieving a state of eight outermost electrons. With this electron transfer, the ionic bond in KCl is formed.

An ionic compound consists of a large network of ions in which positive and negative charges are balanced. In covalent bond, two electrons (one pair) are shared by two atoms. ... LiCl is an ionic compound because Li is a metal (all elements in the first 2 rows are metals) and chlorine is a non-metal.

An ionic compound is named first by its cation and then by its anion. The cation has the same name as its element. For example, K+1 is called the potassium ion, just as K is called the potassium atom.

The molecule overall covalent as dipole of the resultant 3 N-F bond will cancel the lone pair moment on Nitrogen atom as they are operating in opposite directions. If we talk about the bond then each N-F bond is ionic as F is more electronegative than N so each bond dipole will be from N to F.

Ionic compounds are compounds consisting of ions. Two-element compounds are usually ionic when one element is a metal and the other is a non-metal. Examples include: sodium chloride: NaCl, with Na+ and Cl- ions.

1 Expert Answer KCN is the salt of a strong base (KOH) and a weak acid (HCN), and thus the salt in aqueous solution will have a basic pH.

KCl is an ionic compound it does not contain covalent bond.

Potassium iodide (KI) forms an ionic bond. Potassium and iodine have very different electronegativities. The two atoms would form an ionic bond since ionic bonds form between atoms with a large difference in electronegativity (difference>1.7 using the Pauling scale will result in an ionic bond).

Potassium Nitrate is a Ionic bond which are stronger than covalent, hydrogen and metallic bonds.

For example, potassium chloride, KCl, is an ionic compound made up of potassium and chlorine ions. In water, the ions dissolve and dissociate into positively charged potassium ions and negatively charged chlorine ions. Both are attracted to the water molecules and are therefore hydrophilic.

Potassium nitrite (distinct from potassium nitrate) is the inorganic compound with the chemical formula KNO2. It is an ionic salt of potassium ions K+ and nitrite ions NO2−, which forms a white or slightly yellow, hygroscopic crystalline powder that is soluble in water.

The ions from KCl derive from a strong acid (HCl) and a strong base (KOH). Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt. Although the K + ion derives from a strong base (KOH), the NO 2 − ion derives from a weak acid (HNO 2).
