Why is NaCl more ionic than cacl2?

If the lattice energy is lesser the ions are easily formed as they are converted to its solid ionic compound easily. Among the sodium chloride and calcium chloride, NaCl has lesser lattice energy than calcium chloride, so NaCl as an ionic compound formation is easy.

What is the difference between NaCl and MgCl2?

Sodium chloride (NaCl) has a melting point of 801 degree Celsius, while that of magnesium chloride (MgCl2) is 714 degrees Celsius. Both sodium chloride and magnesium chloride are ionic solids. In fact, magnesium chloride has a greater degree of covalency as compared to sodium chloride.

Which is more stable NaCl or MgCl2?

U(MgCl2) = 2477; U(NaCl) = 769 kJ mol^-1 Higher lattice energy implies better stability meaning stronger bonds.

How is NaCl an ionic compound?

Sodium chlorideSodium chloride / IUPAC ID
Ionic compounds, such as sodium chloride (NaCl), are formed by a transfer of electrons that creates ions. Ions exert electrostatic force on each other, which forms ionic bonds. The hydrogen and oxygen atoms in a water molecule, however, are bonded by sharing electrons rather than by transferring them.

Which of the two is more ionic NaCl or any and why?

NaCl is more ionic than NaI because chlorine is more electronegative than iodine.

Is NaCl stronger than CaCl?

You need one sodium atom to provide the extra electron for one chlorine atom, so they combine together 1:1. The formula is therefore NaCl. The ionic bonding is stronger than in sodium chloride because this time you have 2+ ions attracting 2- ions. The greater the charge, the greater the attraction.

Why does NaCl have a higher melting point than MgS?

NaCl because it has a higher melting point, and thus stronger ionic bonds, so it will take more energy to break the bonds. MgS because it has a higher charge (Mg2+ and S2- v.

Why NaCl has lower melting point than MgS?

Explaining melting points The greater the charge on the ions, the stronger the forces holding them together. 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.

Why does NaCl and MgCl2 differ in melting point?

It is because sodium chloride is comparatively more Ionic than magnesium chloride. And more Ionic a compound is, higher its melting and boiling point.

Why MgCl2 is more covalent than NaCl?

The size of magnesium (Mg) is lesser than sodium(Na). Covalent characteristics will be more if the size of the cation is small. Therefore, MgCl2 is more covalent than NaCl.
