Why is the melting point of NaCl higher than that of AlCl3?

Melting point of NaCl is higher than that of AlCl3 because of strong electrostatic forces between oppositely charged ions. On the other hand, AlCl3 is a covalent compound with lesser forces of attraction.

Why AlCl3 has lower melting point than NaCl?

we know that ionic compounds have more melting and boiling points than covalent compounds. NaCl is more ionic than AlCl3 because ionic character depends on size of cations as here anions are same more the size more the ionic character.

Which has the highest melting point NaCl mgcl2 AlCl3 KCl?

NaCl is more ionic than AlCl3 because ionic character depends on the size of cations. As here anions are same, more the size of cation, more the ionic character. So the melting point of NaCl is much higher than that of AlCl3.

Is AlCl3 stronger than NaCl?

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.

Which of the following has highest melting point NaCl?

Oxide anion is a better candidate as compared to the chloride anion. Since, Mg2+ is smaller than Ba2+ and having +2 charge, MgO will have the highest melting point from the given compounds.

Why is the melting point of NaCl higher than that of mgcl2?

Both sodium chloride and magnesium chloride are ionic solids. Also, magnesium is more electronegative as compared to sodium. 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 has highest melting point 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).

Why melting point of NaCl is higher than mgcl2?

Which has highest melting point alcl3?

What is the melting point of alcl3?

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

Which of the following has highest melting point NaCl NaBr?

NaF is the highest melting point halide.

Which of the following has highest melting point?

Tungsten (W) is the metal (in pure form) with the highest melting point with a melting point of 3695 K (3410°C) Also, with a boiling point of 6203 K, Tungsten has the highest boiling point of all metals….Additional Information.

Name of the element	Atomic Number	Melting point
Aluminum (Al)	13	660.3 °C

Why does NaCl have a higher melting point than Al2Cl6?

NaCl has a higher melting point (801°C, 1474°F) than [math]Al_2Cl_6 [/math] (193°C, 379°F). This is because sodium chloride is an ionic compound and aluminum chloride is a simple molecular compound. Aluminum chloride molecules are attracted to each other by van der Waal’s forces.

What is the crystal structure of NaAlCl4 at – 153 °C?

The compound NaAlCl4 with an incongruent melting point at – 153 °C seems well established and its crystal structure has been determined [7] , using a Weissen­ berg camera. It is orthorhombic (s pace group P2,2,2,), with Z = 4 and d (x-ray) = 2.00 g/cm3.

Does NaCl-Aich contain a definite region of immiscibility?

In conclusion, a restudy of the system NaCl-AICh has shown it to contain only one intermediate com· pound and a definite region of liquid immiscibility. Also, temperatures and compositions of invariant points have bee n closely defined.

What is the composition of the aicl3·rich liquid?

The composition of the AICl3·rich liquid, therefore, is 99.6 mol percent AlCh. Several attempts were made to study the closure of the two·liquid dome.
