Is it possible for a polar covalent compound to have a lower melting point than a non-polar covalent compound?
Yes, it is possible. Melting point is influenced by various factors beyond just the polarity of the compound, such as molecular size, shape, and intermolecular forces. A polar covalent compound with weaker intermolecular forces can have a lower melting point than a non-polar covalent compound with stronger intermolecular forces.
Is A compound with a high melting point ionic or covalent?
A compound with a high melting point is more likely to be ionic rather than covalent. Ionic compounds have strong electrostatic forces between oppositely charged ions, resulting in high melting points. Covalent compounds typically have lower melting points because they are held together by weaker intermolecular forces.
What is a compound that's has a low melting point and is ionic and covalent?
One example of a compound with both ionic and covalent character is ammonium chloride (NH4Cl). It has a low melting point due to its ionic interactions between ammonium cations and chloride anions and covalent interactions within the ammonium ion itself.
Why does KBr have a higher melting point than CH3CHO?
KBr has a higher melting point than CH3CHO because KBr is an ionic compound with strong electrostatic forces between its ions, while CH3CHO is a covalent compound with weaker intermolecular forces.
What is the melting point for covalent?
Covalent bonds do not melt. Compounds with covalent bonds melt and the melting point depends primarily on whether there are discrete molecules held together by intermolecular forces (which have lower melting points) or giant covalent networks such as in silica or diamond (which tend to have higher melting points).

What information would the melting point give you in terms of the bonding of a compound?
Ionic compounds have melting points higher than covalent compounds.
Why silve iodideAgI a compound used in photography has much higher melting point than vanillin c8h8O3 a sweet smelling compound used in flavorings?
Silver iodide (AgI) is an ionic compound with strong attractions between oppositely charged ions, resulting in a higher melting point. Vanillin (C8H8O3) is a covalent compound with weaker intermolecular forces, leading to a lower melting point. Ionic compounds typically have higher melting points compared to covalent compounds due to their stronger bonding interactions.
Why is the melting point of sodium chloride is much higher than that of aluminium tetrachloride?
Sodium chloride is an ionic compound whereas AlCl3 is a covalent compound. Ionic compounds have greater melting point due to stronger electrostatic force of attraction.
Does CaO or CS2 have a higher melting point?
CaO (calcium oxide) has a higher melting point than CS2 (carbon disulfide). This is because CaO is an ionic compound with strong electrostatic forces between ions, while CS2 is a covalent compound with weaker intermolecular forces.
Why does KBr have a higher melting point than CH3CHO?
KBr has a higher melting point than CH3CHO because KBr is an ionic compound with strong electrostatic forces between its ions, while CH3CHO is a covalent compound with weaker intermolecular forces.

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 can one determine the melting point of a compound?
To determine the melting point of a compound, one can use a melting point apparatus. The compound is heated gradually until it changes from a solid to a liquid state. The temperature at which this change occurs is recorded as the melting point of the compound.
What has a lower melting point than ionic solids?
Covalent compounds have a lower melting point.
