Concept explainers
(1)
Interpretation:
The chiral centers need to be labeled in the given molecules.
Concept introduction:
Chiral carbon is an asymmetric carbon which contains four different types of groups or atoms. Monosaccharides have one or more chiral centers except dihydroxyacetone.
(2)
Interpretation:
The given molecules need to be classified as D or L monosaccharides.
Concept introduction:
Sugar molecules can name as D or L sugars according to their most oxidized carbon at the top of the Fisher projection.
(3)
Interpretation:
The enantiomers of the given monosaccharide need to be determined.
Concept introduction:
Carbon group with four different groups attached are chiral. Those compounds and their mirror image are non −superimposable and these are called as enantiomers or optical isomers.
(4)
Interpretation:
The Fisher projection of the given monosaccharide needs to be drawn.
Concept introduction:
Fisher projection is a two dimensional representation of a three dimensional molecule.

- For a particular hypothetical reaction, A+B →2C, the value of AG° is -125 kJ/mol. What is the value of AG for this reaction at 35°C when [A] = 0.10 M, [B] = 0.05 M, and [C] = 2.0 × 10¹ M?arrow_forwardIn an experiment, 74.3 g of metallic copper was heated to 100.0°C and then quickly dropped into 200.0 mL of water in a calorimeter. The heat capacity of the calorimeter with the water was 875 J/°C. The initial temperature of the calorimeter was 27.5°C, and the final temperature after addition of the metal was 29.8°C. What is the value of the molar heat capacity of copper?arrow_forwardThe Haber-Bosch process permits the direct conversion of molecular nitrogen to ammonia, which can be used in large-scale fertilizer production. Given the balanced Haber-Bosch reaction and using the bond energies in the table below, estimate the enthalpy change associated with the reaction.
