Alkaloids salts are not very soluble in the organic solvent diethyl ether. What might happen to
the free-base form of caffeine (an alkaloid) dissolved in diethyl ether if gaseous hydrogen chloride,
(a) A second layer of water would form.
(b) Nothing; the
(c) The diethyl ether-insoluble caffeine salt would form as a white pecipitate.
(d) The acid-base reaction would release heat, which would cause the diethyl ether to start evaporating.

They are chair conformations of the same molecule, and they are conformational enantiomers. They are identical conformations of the same molecule. They are different molecules, and they are diastereomers. They are different molecules, and they are enantiomers. O000arrow_forward
- One way to determine a structural defect model (such as that shown in the figure below for a solid solution of Al2 O3 in MgO) is to make careful density measurements. O2- AP+ Mg2+ o Vacancy A substitutional solid solution of Al½O3 in MgO is not as simple as the case of NiO in MgO. The requirement of charge neutrality in the overall compound permits only two Al+ ions to fill every three Mg²+ vacant sites, leaving one Mg²+ vacancy.
