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.

If the freezing point of a particular substance is 52 degrees celsius then what would its melting point be?
The freezing point and melting point of a substance are the same, so the melting point would also be 52 degrees celsius.
Freezing point of pure substance 21 degrees what is the melting point?
The melting point of a substance is the same as its freezing point in a closed system. Therefore, if the freezing point of a pure substance is 21 degrees Celsius, its melting point would also be 21 degrees Celsius.
What does a Graph of melting point and freezing point of naphthalene look like?
The graph of the melting point and freezing point of naphthalene would show a plateau at the melting point, as the solid naphthalene transitions into the liquid phase, and a plateau at the freezing point, as the liquid naphthalene transitions back into the solid phase. The melting point and freezing point of naphthalene are the same at approximately 80 degrees Celsius.
Does platinum have a low melting point?
No, platinum has a high melting point of 1,768 degrees Celsius, making it one of the highest melting metals. This high melting point is one of the reasons why platinum is valued for its durability and resistance to heat.
Why the melting point of arsenic is higher than boiling point?
The melting point is higher than the boiling point of Arsenic only because the melting point is when Arsenic is under pressure because otherwise it would sublimate, or turn directly from a solid to a gas, a the "boiling" point of 614 degrees Celsius and normal atmospheric pressures.
How can a mixed melting point confirm the identity of an unknown compound?
The melting point is not enough to definitely identify the compound because different compounds may have a similar melting point range. It all depends on the compounds. If you have a compound of acetanilide and flourene, the results will lead to similar melting points of 115 degrees Celsius and 116 degrees of Celsius. The ranges will be similar so it would be hard to definitely identify the compound.
Where would you go to find the melting point of a known compound?
Google!
What types of molecules would have the lowest melting point?
Type your answer here... Nonpolar molecules
What effect would too rapid heating have upon apparent melting point of a compound?
Too rapid heating can lead to an inaccurate measurement of the melting point, as the heat may not be evenly distributed throughout the sample, causing the melting point to appear lower than it actually is. This can result in a broadened melting range or even a false melting point. It is essential to heat the sample gradually to obtain an accurate melting point.
Why would the melting point of a molecular compound generally be lower than an ionic compound?
The ionic bond is stronger.
How could you positively identify a compound using only melting point determinations?
I do not believe that any chemist would choose to identify a compound by using only the melting point; why create such difficulties for yourself?
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.
What forces would result in the lowest melting point?
London dispersion forces or Van der Waahls forces
What substance has the lowest freezing point?
Mercury Hg -38.8' Now you could consider Hydrogen to be a metal if you are willing to get creative with the definition of metal. In that case it would be −259.16 °C
Which compound has a high melting point covalent and non metals?
A possible compound would be silicon dioxide with giant covalent structure and strong covalent bonds.
How do impurities affect the melting point of compound?
effects that impurities have on melting point iof a pre compound. I learned that it is because the impurities "defect" the crystal lattice of the compound. A pure compound is a structure of high molecular symmetry. An impurity is rather assymetrical, or is a poorly organized structure. If the impurites are present with the pure compound, the melting point will deviate because melting point is also dependent on the high symmetry and organization of molecular structures,
You are given the melting points of three unknown substances and are asked to predict which one is an ionic compound You would select the compound with the?
Highest melting point. (Note that this does not assure that the remaining compounds are not also ionic.)
