Which compound would you expect to have the highest boiling point Why?

Ionic compounds have higher melting points than covalent compounds with small molecules. So the answer must be NaCl or MgO .

What compound would you expect to have the highest boiling point?

Among the given options, (c) ethanol has the highest boiling point as it has the strongest intermolecular force of hydrogen bonding.

Which compound has the higher boiling point and why?

First there is molecular size. Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. It is very important to apply this rule only to like compounds.

Which compound will have the highest boiling point quizlet?

I2 has the highest boiling point because it has the highest molar mass. Because the halogens are all similar in other ways, you would expect I2 to have the greatest dispersion forces and therefore the highest boiling point (and in fact it does).

Which compound will have the highest melting point?

MgO has the highest melting point, by a large margin.

What determines boiling point?

Types of Molecules: the types of molecules that make up a liquid determine its boiling point. If the intermolecular forces between molecules are: relatively strong, the boiling point will be relatively high. relatively weak, the boiling point will be relatively low.

Which compound has the highest boiling point ch3ch2ch3?

Ethyl alcohol undergoes extensive hydrogen bonding and thus has the highest boiling point.

What type of compound has high melting point why?

Ionic compounds properties

Ionic compounds have an equal number of positive and negative ions arranged in the three-dimensional lattice due to which they have high melting points. The strong force of attraction between oppositely charged ions means that ionic compounds have high melting and boiling points.

Why do ionic compounds have high melting point?

Ionic compounds are held together by electrostatic forces between the oppositely charged ions . … As the ionic lattice contains such a large number of ions, a lot of energy is needed to overcome this ionic bonding so ionic compounds have high melting and boiling points.

Which ionic compound has highest melting point?

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.
