Ethanethiol (CH3CH2SH, pKa=10.6) was named the smelliest substance in existence. Draw the equilibrium that forms when ethanethiol is added to a solution buffered at pH 9, and show the relative proportions of all organic species.

What is the hybridization of each carbon in the molecule of ethanol. CH3 = sp3 CH2OH = sp3 I think that the carbons are all sp3 because there are only single bonds in this molecule. Is this correct?

Last question, I just want to make sure I understand the concept of hybridization. For carboxylic acid the hybridization is: CH3= sp3 because there are only single bonds COOH= Sp2 because the oxygen is double bonded to the C Is this correct? Thank you for
