6. Classify each compound as ionic or molecular based on its properties. Substance Melting Point Solubility Conductivity Classification
1 -55 oC poor poor
2 396 oC good good
3 0 oC not tested poor
4 200 oC good good
5 20 oC good poor

1.  c

2. ionic

3. c

4. ionic

5. alloy or ionic

Explanation:

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.  

its going to be mutualism cuz they both benefit from the relationship.
