A molecule is composed of carbon atoms connected to 3 hydrogen atoms and a hydroxide. A hydroxide is a made up of an oxygen atom bonded to a hydrogen atom. How many different types of atoms make up one molecule of methanol? A. 3
B. 4
C. 5
D. 6

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.
