Solutions for Chapter 34: Particle Size Determination
Full solutions for Principles of Instrumental Analysis | 6th Edition
An object that lacks chirality; an object that has no handedness
acid ionization constant (Ka).
The equilibrium constant for the acid ionization. (15.5)
The basic unit of an element that can enter into chemical combination. (2.2)
axis of symmetry
An axis about which a compound possesses rotational symmetry.
The process by which a liquid rises in a tube because of a combination of adhesion to the walls of the tube and cohesion between liquid particles. (Section 11.3)
A microcrystalline form of carbon. (Section 22.9)
The angle by which two groups are separated in a Newman projection.
Compounds formed when hydrogen reacts with alkali metals and also the heavier alkaline earths (Ca, Sr, and Ba); these compounds contain the hydride ion, H-. (Section 22.2)
The energy that an object possesses by virtue of its motion. (Section 5.1)
The arrangement in space of the atoms of a molecule. (Section 9.2)
A macromolecule containing many amino acid units, each joined to the next by a peptide bond
A group that is used during synthesis to protect a functional group from the reaction conditions.
A term used to designate the configuration of a chirality center, determined in the following way: Each of the four groups is assigned a priority, and the molecule is then rotated (if necessary) so that the #4 group is directed behind the page (on a dash). A clockwise sequence for 1-2-3 is designated as R.
Rate determining step
The step in a multistep reaction sequence that crosses the highest energy barrier.
A compound that can be used to achieve the resolution of enantiomers.
The amount of time required for a compound to exit from a gas chromatograph.
Matter that has both a definite shape and a definite volume. (Section 1.2)
A reaction that disobeys conservation of orbital symmetry.
van der Waals radius
The minimum distance of approach to an atom that does not cause nonbonded interaction strain.
Williamson ether synthesis
A method for preparing an ether from an alkoxide ion and an alkyl halide (via an SN2 process).
