Problem- Please provides the mechanism for the reaction of methyl propanoate with LiAlH4.
Please be comprehensive and as clear as you can be.
To 1.00 L of a 0.100 M aquoeus solution of the weak base pyridine C5H5N is added 1.00 ml of 14.0 M NaOH. What fraction of the pyridine molecules in the resulting solution react with water to release hydroxide ions? (Kb C5H5N = 1.7 x 10^-9)
