This can be rationalised by looking at the lattice energy. Using Madelungs method the smaller Na+ ion causes a stronger coulombic attraction making it harder to beak up the lattice and increasing the mp.

Which is faster to melt glucose or sodium chloride?
Glucose (Melting point: 146° C) will melt faster than NaCl (Melting point: 801° C)
Why mo has high melting point tha nacl?
The simple explanation- it takes less energy to beak up the ionic lattice of NaCL than it does to break up the metallic lattice of Mo. Molybdenum is high melting metal, mp. ca. 2600 C. (thats really hot!) The reasons why some metals are high melting and some are low is complex. In simple terms Mo has a very strong metallic bond. Nacl is an ionic compound, these generally have high melting ponts NaCl is ca 800 C (thats also very hot but obviously much less than Mo. Predicting melting ponts is difficult.
Is there a metal with a higher melting point than gold?
Tungsten. It has high melting point than gold because it is used in lightbulb.
Why does water have a higher melting point than oxygen?
Water has a high melting point and boiling point because of hydrogen bonds
Dose Cacl2 have the highest melting point?
No, CaCl2 does not have the highest melting point. CaCl2 has a melting point of 772 degrees Celsius, which is relatively high for a salt compound. However, there are other compounds such as tungsten (melting point of 3,422 degrees Celsius) and carbon (melting point of 3,550 degrees Celsius) that have higher melting points.
Is the melting point of BaCl2 higher than the melting point of CaCl2?
Yes; the M.P of BaCl2 is about 963 Celsius while that of CaCl2 is about 782Celsius.
Which material has higer melting point NaCl or sugar explain?
Generally inorganic ionic salts have higher melting points than organic materials; the bonds are stronger.
Why is the melting point of diamond higher than sulfur?
diamond has a 3 dimensional frame work of carbon and hence has high melting point
Can melting point distinguish table salt and table sugar?
Salt or NaCl, has much stronger inter-molecular bonds that form a giant ionic structure in a tight latice. This is because NaCl molecules form stronger bonds than C12H22O11 because NaCl is smaller and it consists of fewer molecules. Being a compound of sodium which is a highly reactive and strong element, salt is much more stable than the carbon compound of sugar. Melting only requires breaking the intermolecular bonds which is difficult in sodium's case.
Does glass have a high melting point?
Glass has a higher melting point than most clear objects, second to that of rare gems like diamonds, sapphire, and rubies.
What happens if boiling point is higher than melting point?
The boiling point is always higher than the melting point.
Why does stearic acid has a high melting point than oleic?
The carbon chain of stearic acid is longer; more long chain, higher melting point.The melting point of stearic acid is 69,3 0C and the melting point of oleic acid is 14 0C.
