1mole of mgcl2 is dissolved in 1 l of water. which of the following is true?
a. mgcl2 exists at a concentration of 1m
b. mg2+ exists at a concentration of 1m
c. cl- exists at a concentration of 1m
d. none of the above
e. all of the above

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.
