Consider the two Lewis structures given below: Lewis representation of BCl3 Lewis representation of NH3 Which of the following statements is correct? Structure 2 can be classified as both a Brønsted–Lowry and a Lewis base. In a reaction, structure 1 would function as a Lewis base while structure 2 would function as a Lewis acid. Structure 2 would have similar Lewis acid–base properties as those of AlCl3. Structure 1 can be classified as both a Brønsted–Lowry and a Lewis aci

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.
