Madam Susan performed a demonstration to show one properties of acid in the fume chamber. She dropped the concentrated acid onto a piece of filter paper. What happen to the filter paper? Explain your answer.​

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.  

c is the correct answer on the lab
