Is Ionic bond have higher melting and boiling point than covalent bond?

Ionic compounds generally have a higher melting point. This is because the bonds between the negative and positive ions are strong, and this keeps the solid together as the temperature rises. Covalent compounds have comparatively weak bonds between the molecules, so as the temperature rises, these bonds are broken easily and the substance turns into a liquid.

∙ 11y agoIonic compounds generally have high melting points and boiling points with some notable exceptions e.g. NH4Cl which sublimes.
Metals also generally have high melting points and boiling points, again there are some notable exceptions Mercury a liquid at room temperture, gallium which melts in your hand.

∙ 15y agoYes, an ionic bond has a higher melting and boiling point than a covalent bond
ionic bond>covalent bond>metallic bond>hydrogen bond>vanderwaals.....
Wiki User
∙ 13y agoIonic bonds are stronger than covalent bonds, so it takes more energy to break the bond and force the atoms apart
Wiki User
∙ 14y agocovalent- less(due to weak Van der Waals forces)
ionic-more (due to strong bond)

Which substance ionic or covalent has a higher melting point?
Generally the ionic molecules has a higher melting point.
How are ionic and covalent compounds different in terms of melting and boiling point and electrical conductivity and hardness and brittleness?
Ionic compounds generally have higher melting and boiling points.
Do ionic compounds have lower boiling points than polar covalent?
Ionic compounds have higher boiling points than covalent compounds.
Why the melting and boiling point of covalent compound are low?
Compared to ionic compounds, covalent compounds have relatively low melting and boiling points because covalent bonds are not as strong as ionic bonds, and it is the bonds which hold materials together in the solid, or more solid phases.
Who has higher melting points ionic compounds or covalent compounds?
Ionic compounds have higher melting points than covalent compounds. Common table salt, sodium chloride, is an ionic compound and has a melting point of 801 oC. Table sugar, sucrose, a covalent compound, has a melting point of about 186 oC.
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.
Which substance ionic or covalent has a higher melting point?
Generally the ionic molecules has a higher melting point.

Ionic compounds generally have higher melting and boiling points.
Do ionic compounds have lower boiling points than polar covalent?
Ionic compounds have higher boiling points than covalent compounds.

Why an ionic bonds have higher melting than a covalent bonds?
The ionic bond is stronger.
Are melting points of covalent compounds high or low compared to ionic compounds?
Ionic compounds have strong electrostatic force of attraction and hence have higher melting points than covalent compounds.
Is Nickel Sulfide an Ionic Bond?
No. The electronegativity difference is 0.67, giving Ni - S bonds 11% ionic character. The bonds have substantial covalent character, instead. The high melting and boiling points of NiS can be attributed, not to the ionic character, but to the network arrangement of atoms. Networks, whether they be predominately ionic or predominately covalant, have higher melting and boiling points.
what has higher melting points ionic or covalent compounds?
Ionic compounds have higher melting points because the bond olding the ionic crystal together is stronger than the intermolecular forces (van der Waals) holding covalent molecules together. Giant covalent molecules such as dialmond and silicon dioxide have very high melting points because the lattice is held together by stong covalent bonds
What are two physical properties that differ between covalent and ionic bonds?
There are more than two. In general: Covalent compounds have low melting and boiling points while ionic compounds have high melting and boiling points. Ionic compounds are good conductors of electricity when melted, while covalent compounds are not. Ionic compounds are soluble in water, while covalent compounds are soluble in non-polar liquids. These are the essentials, but other differences exist. All of these are generalizations, exceptions do occur.
Which type of compound would have the lowest melting point?
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.
