Consider the equation: a+> 4c. if 3.0 moles of a is reacted with 6.0 moles of b, which of the following is true after the reaction is complete? explain your answer.
a.) a is the leftover reactant b/c you only need 2 moles of a and have 3.
b) a is the leftover reactant b/c for every 1 mole of a, 4 moles of c are produced.
c) b is the leftover reactant b/c you have more moles of b than a.
d) b is the leftover reactant b/c 3 moles of b react with every 1 mole of a.
e) neither reactant is leftover.

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.
