Draw the isomeric alcohols (C6H14O) that can be synthesized via a sodium borohydride reduction of an aldehyde.

The rate of a first-order reaction is followed by spectroscopy, monitoring the absorption of a colored reactant at 520 nm. The reaction occurs in a 1.09-cm sample cell, and the only colored species in the reaction has an extinction coefficient of
$6100cm^{-1}M^{-1}$
at 520nm .

a)Calculate the initial concentration of the colored reactant if the absorbance is 0.605 at the beginning of the reaction.

b) The absorbance falls to 0.274 at 24.2. Calculate the rate constant in units of.

c)Calculate the half-life of the reaction.

d)How long does it take for the absorbance to fall to 0.144?
