What is the difference between a chemical formula and a molecular formula.

Molecular formula indicates the simple number of each type of atom in molecule with no information on structure. Chemical formula is a way of presenting information about the chemical propagation of atom that constitute a particular chemical compound or molecule, using chemical element symbols.

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.
