Why do saturated fatty acids have straight structures, while unsaturated fatty acids have bent structures?
a. saturated fatty acids have a larger mass.
b. saturated fatty acids contain many more bonds.
c. saturated fatty acids have single carbon-to-carbon bonds.
d. saturated fatty acids contain more carbon atoms.

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.
