Match each description with the VSEPR molecular geometry. All descriptions are of the regions around the central atom. (ER = electron region; ERG = electron region geometry; MG = molecular geometry; LP = lone pair; BA = bonding area) 1 BA between 2 atoms
4 ER (as 2 LP + 2 BA) or 3 ER (as 1 LP + 2 BA)
3 ER consisting of 0 LP and 3 BA
4 ER consisting of 1 LP and 3 BA
4 ER consisting of 0 LP and 4 BA

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.
