Why boiling point of KCl is high?

Complete answer: Potassium chloride, KCl is an ionic compound formed from potassium cation and chloride anion. Ionic bonds are a result of electron transfer, and hence they are strong bonds that require high melting and boiling points to break the bonds.

How do you know which compound has a higher melting point?

In general, the greater the charge, the greater the electrostatic attraction, the stronger the ionic bond, the higher the melting point.

Is KCl highest melting point?

KCl has high melting point because of strong bonding between K(Potassium)and Cl(chlorine). Hence KCL has the high melting point… Hope it helpful!!!!

Which has high melting point NaCl or KCl?

Answer: NaCl has higher lattice enthalpy than KCl thus its melting point also becomes higher.

Is KCL highest melting point?

Why does KCL have a higher boiling point than h2o?

16) Which member of each of the following pairs of substances would you expect to have a higher boiling point? Explain your answers. a) O2 or Cl2 Both are nonpolar, but Cl2 is larger and so should have stronger dispersion forces between molecules, and so a higher boiling point.

Why NaCl has high boiling point than KCl?

Sodium chloride has a high melting and boiling point There are strong electrostatic attractions between the positive and negative ions, and it takes a lot of heat energy to overcome them.

Which molecule has the 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 ionic compound has a higher melting point?

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.

Which of the following substances has the highest melting point a NaCl B KCl C MgO?

Option (2) MgO is correct. Melting points depend on lattice energy, NaCl and KCl have unit charge on their ions while MgO and BaO have two unit of charge, therefore lattice energies of MgO and BaO are expected to be larger than those of NaCl and KCl.
