Anna stated that ionic compounds have high melting points and low boiling points. she said that this demonstrates that ionic compounds have strong bonds because a lot of energy is needed to break the electrical forces that hold the bonds together.

which statement best describes anna’s error?

a. strong electrical forces will make ionic compounds have high boiling points.

b. strong electrical forces will make ionic compounds have weak bonds.

c. a low amount of energy is needed to break the bonds in ionic compounds.

d. gravitational forces hold the bonds together in ionic compounds.

Anna concluded that ionic compounds have strong bonds because a lot of energy is needed to break the electrical forces that hold the bonds together. This was the error that she made. As strong ionic bonds are formed due to electrostatic force of attraction between two oppositely charged ions. To break these bonds usually high amount of energy is required. Because of the ionic bonds between the ionic compounds they have high melting and boiling points. It is mainly formed between a cation which is mainly a metal and an anion which is an non-metal.

The correct option is a.

Explanation: Ionic compounds are the compounds that are formed by the complete transfer of electrons from one element to another.

The element that donates electron forms a cation and the one which accepts the electron forms anion.

The bond between the cation and anion is the strongest and hence, require alot of energy to break these bonds.

Due to this high amount of energy, these compounds have high melting and boiling points.

Hence, Anna's error was in Statement a.

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
