And the base is going to form a bond with that proton like that. So this is an acid base reaction. So if we react an alcohol with a strong base-- So this is a strong base here-- we're going to form the conjugate base to an alcohol which is called an alkoxides. So this is an alkoxides ion right here. So it's a chemical property of alcohols. Find and create gamified quizzes, lessons, presentations, and flashcards for students, employees, and everyone else.
