Concept explainers
(a)
Interpretation:
The structure of the salmeterol should be drawn.
Concept Introduction:
(b)
Interpretation:
One chirality center in a salmeterol molecule should be identified.
Concept Introduction:
Chirality is the presence of an asymmetric carbon center in a molecule and a molecule which contains a chiral center cannot superimpose on its mirror image. To consider as chiral, molecule or object and its mirror image should not superimpose. To consider as achiral, molecule or object and its mirror image should be superimposed with each other.
In the above diagram, where C is the chiral center/ asymmetric carbon center.
A, B, D, E are four different
(c)
Interpretation:
Enantiomers of salmeterol in three dimensions should be drawn.
Concept Introduction:
Mirror image of a molecule is a reflected duplicate of the molecule.
Enantiomers − the mirror image of the original molecule of a chiral molecule. These are stereoisomers.

- In intercalation compounds, their sheets can be neutral or have a negative or positive charge, depending on the nature of the incorporated species and its structure. Is this statement correct?arrow_forwardThis thermodynamic cycle describes the formation of an ionic compound MX2 from a metal element M and nonmetal element X in their standard states. What is the lattice enthalpy of MX2 ? What is the enthalpy formation of MX2 ? Suppose both the heat of sublimation of M and the ionization enthalpy of M were smaller. Would MX2 be more stable? Or less? or impossible to tell without more information?arrow_forward7. Draw the mechanism to describe the following transformation: Note: This is a base catalyzed reaction. So, the last steps must make [OH]- OH [OH]¯ OH Heat Oarrow_forward

QUESTION Liquid A is known to have a lower viscosity and lower surface tension than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment Liquid A and Liquid B are each pumped through tubes with an inside diameter of 27.0 mm, and the pressures PA and PB needed to produce a steady flow of 2.4 mL/s are measured. 25.0 mL of Liquid A are poured into a beaker, and 25.0 mL of Liquid B are poured into an identical beaker. Stirrers in each beaker are connected to motors, and the forces FA and FB needed to stir each liquid at a constant rate are measured. predicted outcome OPA will be greater than PB OPA will be less than PB OPA will be equal to PB It's impossible to predict whether PA or PB will be greater without more information.…arrow_forward
