Which has a higher melting point NaCl or AlCl3?

As the electrons are shared among the bonded atoms, these compounds exhibit lower melting points and electrical conductivity compared to ionic compounds. Hence \[NaCl\] (an ionic compound) has a higher melting point than \[AlC{l_3}\] (A covalent compound).

Which is stronger NaCl and AlCl3?

NaCl is more ionic than AlCl3. In AlCl3, the charge of the cation Al3+ is higher when compared to Na+ while the anion Cl is the same in both the compounds. Therefore, according to Fajan’s rule, AlCl3 is more covalent than NaCl.

Why is the melting point of sodium chloride higher than that of Aluminium chloride?

Answer: the ionic character of NaCl is more than that of AlCl3 because small cation and large anion favours covalency (fajan’s rule ) and therfore AlCl3 is more covalent and hence it’s melting point is less than NaCl.

What has a higher melting point than NaCl?

Magnesium oxide
Explaining melting points Sodium chloride is made from Na + ions and Cl – ions and has a melting point of 801°C. Magnesium oxide is made from ions with two charges (Mg 2+ and O 2-) and so has a much higher melting point of 2852°C.

What is the melting point of AlCl3?

378.3°F (192.4°C)
Aluminium chloride/Melting point

Is AlCl3 more soluble than NaCl?

More polar compounds are more soluble in water. Here among NaCl and AlCl. Similarly when the hydration energy is more than the lattice energy the compound is more soluble in water. NaCl is having more hydration energy than lattice energy so its soluble in water quickly than AlCl3, which is having more lattice energy.

Which has higher melting point MgCl2 or NaCl?

Sodium chloride (NaCl) has a melting point of 801 degree Celsius, while that of magnesium chloride (MgCl2) is 714 degrees Celsius. These factors combine to result in a higher force of attraction in sodium chloride as compared to magnesium chloride and hence a higher melting point for the former.

Which chloride has the highest melting point?

Sodium chloride (NaCl)
Sodium chloride (NaCl) The strong attractions between the positive and negative ions require a large amount of heat energy to break, so sodium chloride has high melting and boiling points.

Which compound has the highest melting point?

Tantalum carbide (TaC) and hafnium carbide (HfC) are of particular interest due to their high melting temperatures (>4000 K) which are the highest reported among all known inorganic materials1,2,3.
