(a)

Interpretation Introduction

Interpretation:

Conversion of oleic acid into the given set of compounds is done by reagents and the same has to be identified.

Concept introduction:

Hydrogenation is a reaction where hydrogen is added to a compound to get the product in the reduced form.  Few examples are, unsaturated compounds are converted to saturated compounds,  ketone to alcohol, carboxylic acid to alcohol etc.

To identify: the reagents used for transformation of oleic acid into stearic acid.

Carboxylic acid to alcohol requires a strong reducing agent such as LAH .

To identify: the reagents used for conversion of oleic acid to 1-octadecanol.

(d)

Interpretation Introduction

Interpretation:

Conversion of oleic acid into the given set of compounds is done by reagents and the same has to be identified.

Concept introduction:

Ozonolysis of the an alkene by use of ozone yields two aldehyde.

Aldehyde when undergoes oxidation using a strong oxidizing agent gives carboxylic acid as the product.

To identify: the reagents used for conversion of oleic acid to nonanedioic acid.

An open vessel containing water stands in a laboratory measuring 5.0 m x 5.0 m x 3.0 m at 25 °C ; the vapor pressure (vp) of water at this temperature is 3.2 kPa. When the system has come to equilibrium, what mass of water will be found in the air if there is no ventilation? Repeat the calculation for open vessels containing benzene (vp = 13.1 kPa) and mercury (vp = 0.23 Pa)
Every chemist knows to ‘add acid to water with constant stirring’ when diluting a concentrated acid in order to keep the solution from spewing boiling acid all over the place.  Explain how this one fact is enough to prove that strong acids and water do not form ideal solutions.
The predominant components of our atmosphere are N₂, O₂, and Ar in the following mole fractions: χN2 = 0.780, χO2 = 0.21, χAr = 0.01. Assuming that these molecules act as ideal gases, calculate ΔGmix, ΔSmix, and ΔHmix when the total pressure is 1 bar and the temperature is 300 K.
