Full solutions for Organic Chemistry | 7th Edition
Compounds with a carbonyl functional group and the general formula RCHO, where R is an H atom, an alkyl, or an aromatic group. (24.4)
A group derived by removing a hydrogen from an alkane; given the symbol R!
A unit of energy; it is the amount of energy needed to raise the temperature of 1 g of water by 1 °C from 14.5 °C to 15.5 °C. A related unit is the joule: 1 cal = 4.184 J. (Section 5.1)
The potential difference between the cathode and anode in an electrochemical cell; it is measured in volts: 1 V = 1 J>C. Also called electromotive force. (Section 20.4)
The most stable nonplanar conformation of a cyclohexane ring; all bond angles are approximately 109.5°, and all bonds on adjacent carbons are staggered.
In UV-Vis spectroscopy, the region of the molecule responsible for the absorption (the conjugated p system).
A property of a solvent (vapor-pressure lowering, freezing-point lowering, boiling-point elevation, osmotic pressure) that depends on the total concentration of solute particles present. (Section 13.5)
A polymer,that is formed via a condensation reaction.
In an acid-base reaction, the product that results when an acid is deprotonated.
A polymer containing two or more different monomers. (25.2)
A derivative of a carboxylic acid in which H of the carboxyl group is replaced by a carbon.
The energy released when 1 g of a substance is combusted. (Section 5.8)
In an exothermic process the transition state is closer in energy to the reactants than to the products, and therefore the structure of the transition state more closely resembles the reactants. In contrast, the transition state in an endothermic process is closer in energy to the products, and therefore the transition state more closely resembles the products.
A series of atoms, ions, or molecules having the same number of electrons. (Section 7.3)
lambda max (lmax)
In UVVis spectroscopy, the wavelength of maximum absorption.
A compound capable offunctioning as an electron pair donor.
Refers to groups occupying l,4-positions on a benzene ring
The arrangement of elements in order of increasing atomic number, with elements having similar properties placed in vertical columns. (Section 2.5)
The sulfur analog of an ether; a molecule containing a sulfur atom bonded to two carbon atoms. Sulfi des are also called thioethers
Constitutional isomers in equilibrium with each other that differ in the location of a hydrogen atom and a double bond relative to a heteroatom, most commonly O, N, or S.
