A chemist prepares a solution of nickel(II) chloride by weighing out of nickel(II) chloride into a volumetric flask and filling the flask to the mark with water. Calculate the concentration in of the chemist's nickel(II) chloride solution. Be sure your answer has the correct number of significant digits.

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.
