Solutions for Chapter 10: Alkynes

The electrode at which oxidation occurs. (18.2)

Valence electrons involved in forming a covalent bond (i.e., shared electrons).

A term describing a molecule or an ion that cannot be superimposed on its mirror image. (Sections 23.4 and 24.5)

A band of molecular orbitals lying higher in energy than the occupied valence band and distinctly separated from it. (Section 12.7)

Stereoisomers that are not mirror images of one another.

The branch of chemistry that deals with the relationships between electricity and chemical reactions. (Chapter 20: Introduction)

A substance that consists of a single enantiomer, and not its mirror image.

A higher energy state than the ground state. (Section 6.3)

Chemistry that promotes the design and application of chemical products and processes that are compatible with human health and that preserve the environment. (Section 18.5)

A compound containing a halogen atom covalently bonded to an sp3 -hybridized carbon atom. Given the symbol R!X.

The absolute temperature scale; the SI unit for temperature is the kelvin. Zero on the Kelvin scale corresponds to -273.15 °C. (Section 1.4)

A representation of covalent bonding in a molecule that is drawn using Lewis symbols. Shared electron pairs are shown as lines, and unshared electron pairs are shown as pairs of dots. Only the valence-shell electrons are shown. (Section 8.3)

The number of molecules that participate as reactants in an elementary reaction. (Section 14.6)

A simple sugar, most commonly containing six carbon atoms. The joining together of monosaccharide units by condensation reactions results in formation of polysaccharides. (Section 24.8)

A way to view a molecule by looking along a carbon-carbon single bond

The step in a multistep reaction sequence that crosses the highest energy barrier.

A bond that is characterized by circular symmetry with respect to the bond axis.

Polymers that are formed under conditions in which the individual monomers react with each other to form oligomers, which are then joined together to form polymers.

Compounds with the following structure: R!C#C!H

Reduction of the C"O group of an aldehyde or ketone to a CH2 group using hydrazine and a base. Ylide (Section 16.6)
