Verified step by step guidance1
Identify the base in the given problem. Methanol (CH₃OH) is the base in this context.
Understand the concept of a conjugate acid. A conjugate acid is formed when a base gains a proton (H⁺).
Add a proton (H⁺) to the methanol molecule. This involves adding an H⁺ ion to the oxygen atom in CH₃OH.
Write the chemical formula of the resulting conjugate acid. When CH₃OH gains an H⁺, it becomes CH₃OH₂⁺.
Verify the structure and charge of the conjugate acid. The addition of a proton results in a positive charge, confirming the formula CH₃OH₂⁺.
