Butanol

A higher alcohol with a four carbon atoms and a general formula of C₄H₁₀O. There are four different isomeric structures for butanol:

 butan-1-ol         CH3-CH2-CH2-CH2-OH

 butan-2-ol         CH3-CH2-CH(OH)-CH3

 sec-butanol        CH3-CH-CH3
                        |
                        CH2OH

                       OH
                       |
 tert-butanol      CH3-C-CH3
                       |
                       CH3

These butanol isomers, due to their different structures, have somewhat different melting and boiling points. All are moderately miscible in water and used as a base for perfumes[?]. Like all alcohols, they are poisonous.
