Which is more ionic BeCl2 or BaCl2?

“BeCl2 is largely covalent but BaCl2 is largely ionic in nature”-explain on the basis of polarization.

Which has highest melting point BeCl2?

All the given compounds contain group 2 elements. For example, barium has larger atomic size as compared to all the elements of group 2. So, will have the highest melting point.

Which of the following has lowest melting point BaCl2 srcl2 CaCl2 BeCl2?

BaCl2 is having the lowest melting point as its having less density. More the volume less will be the density and its having weaker bond.

Why BeCl2 has high boiling point?

becl2 has the highest boiling point. Explanation: This is an ionic compound. And according to the feature of e ionic compounds they have high melting points as they are ionically charged particle,they need more heat.

Why does barium chloride have a high melting point?

It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points.

Why melting point of BaCl2 is higher than BaCl2?

Within ionic compounds, a greater melting point can be caused by a higher ionic charge or a higher charge density/better interaction. Since both have the same charge while sodium has a smaller ionic radius, the sodium-based crystal is held together better due to more interaction than the caesium based one.

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.

Which has highest melting point?

The metal with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as electrical filaments in incandescent lamps.

Why does lithium chloride have a high melting point?

LiCl is predominantly ionic in comparison toLiBr. Here the cation is same ,so the bigger the anion,more the covalent character and therefore LiCl is ionic which implies its melting point is higher.

Is BeCl2 polar or non-polar?

BeCl2 is non -polar because the difference in electronegativity between Be (smaller ionic radius than Ba) and Cl is not sufficient to form an ionic bond whereas BaCl2 is a polar compound. Bonds in polar compounds are stronger due to coulombic attraction between ions of opposite charges which means a lot of energy is required to break ionic bonds.

What is the Order of electronegativity difference between BeCl2 MgCl2 CaCl2 BaCl2?

The order is BeCl2,MgCl2, CaCl2 ,BaCl2. The metallic property increases down a group thus the electronegativity difference between them increases on going down the group of alkaline earth metals because the electronegativity decreases down the group due to increase in the atomic size.

Which compound has greater ionic character – BCl3 or CCl4?

Electronegativit of Boron is less than that of Carbon. Hence the B-Cl bond has greater electronegativity difference than C-Cl bond. So we can conclude that Bcl3 would have greater ionic character than CCl4. Having said this, I would like to tell you that both are primarily covalent compounds (ionic character is too small).

Why does sodium chloride have a higher melting point than caesium chloride?

Sodium chloride and caesium chloride are both primarily ionic compounds. Within ionic compounds, a greater melting point can be caused by a higher ionic charge or a higher charge density/better interaction.
