Consider the following statements about alcohols: (i) Alcohols contain a polar O–H bond and hence mix well with polar solvents like water. (ii) Alcohols form hydrogen bonds with water. (iii) Alcohols have a higher boiling point compared to hydrocarbons with the same number of carbon atoms. (iv) For the most part, alcohols are toxic. Which statement(s) is(are) true?

Organic and biological chemistry is a branch of chemistry that studies the synthesis, structure, and function of organic and biologically relevant molecules. It also studies reaction mechanisms.  Organic chemistry is the study of carbon compounds. It focuses on reactions that happen in water at about pH 7, and on sugars.  Biochemistry is another branch of chemistry that studies reactions and processes that happen inside living organisms. It focuses on reactions that happen in living cells.  Bioorganic chemistry involves the study of biological processes using chemical methods. Organic... Show more
