Chapter 7, Problem 37P

(a)

Interpretation Introduction

Interpretation:

Synthesis method of the given compound has to be given from the compound which have the same number of carbon atoms.

Concept Introduction:

Addition of water to alkynes in presence of acid:

Under acidic conditions, alkyne reacts with water to produce an enol which then immediately converts into ketone.  For terminal alkynes, there is a need of catalyst which is mercury.

The formed enol and ketone are called keto-enol tautomers.

Tautomerization: It is the process of inter conversion of tautomers and therefore the process can also be called as keto-enol tautomerization.

Hydroboration reaction:

It is the reaction in which an internal alkyne is converted into ketone.  The reagents used for the hydroboration oxidation reaction is either BH3orR2BH.

A certain half-reaction has a standard reduction potential Ered +1.26 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box.. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box. yes, there is a minimum. 1 red Πν no minimum Oyes, there is a maximum. 0 E red Dv By using the information in the ALEKS…
