What is the total number of covalent bonds in methanol ?

Result
Your answer: —  Â·  Correct: C
Explanation

Methanol (CH3OH) is a simple organic molecule where atoms are held together by covalent bonds formed through electron sharing [1]. To determine the total number of covalent bonds, one must examine its Lewis structure. The central carbon atom forms four covalent bonds to complete its octet: three single bonds with three hydrogen atoms (C-H) and one single bond with the oxygen atom (C-O). The oxygen atom, which requires two bonds to complete its octet, forms one bond with the carbon atom and one single bond with the remaining hydrogen atom (O-H). Summing these up, there are 3 (C-H) + 1 (C-O) + 1 (O-H) = 5 covalent bonds in total. Each bond represents a shared pair of electrons between the participating atoms [1].
