Q. The electrons of an atom that are highest in energy and in the outermost orbitals.
Ans → Valence Electrons
Explanation →
Q. A hydrocarbon that can undergo addition reactions, meaning it contains a double or a triple bond.
Ans → Unsaturated Hydrocarbons
Explanation →
Q. Molecules that have the same molecular formula and sequence of atoms yet differ in their 3-D orientation.
Ans → Stereoisomer
Explanation →
Q. The ability of electrons to "shuffle," or alternate, between bonds, making the molecule extremely stable. The best example of this is benzene.
Ans → Resonance
Explanation →
Q. A polypeptide composed of amino acids bonded together by peptide bonds.
Ans → Proteins
Explanation →
Q. Large macromolecules composed of many similar (sometimes identical) smaller molecules, or monomers, linked together.
Ans → Polymers
Explanation →
Q. Name the rule that states that atoms will lose, gain, or share electrons in order to achieve a filled valence shell, to complete their octet.
Ans → Octet Rule
Explanation →
Q. Biological molecules, such as DNA and RNA, composed of a nitrogen base, a pentose sugar, and a phosphate group.
Ans → Nucleic Acids
Explanation →
Q. Name the formula that shows the number and kinds of atoms in a molecule.
Ans → Molecular Formula
Explanation →
Q. A chemical formula where electrons are represented with dots. Covalent bonds are represented with a line connecting two atoms—the line represents two electrons.
Ans → Lewis Structure
Explanation →
Q. A functional group consisting of an internal carbonyl group (C=O) bonded to two other carbon atoms
Ans → Ketones
Explanation →
Q. Compounds that have the same molecular formula but different structural formulas
Ans → Isomer
Explanation →

Q. The phospholipid that prevents the adherence of inner surfaces of lungs
Ans → Dipalmitoyl lecithin
Explanation →
Q. The migration of a double bond in a 3-carbon system from carbon atoms one and two to carbon atoms two and three
Ans → allylic rearrangement
Explanation →
Q. A substance that cannot be divded chemically into component substances.
Ans → element
Explanation →
Q. A bond formed from the electrostatic attraction between ions with different charges. This typically consists of a metal (cation) and a nonmetal (anion). A metal loses electrons to form a cation and some non-metal gains those electrons to form an anion.
Ans → Ionic Bond
Explanation →
Q. The percentage of yield that occurred versus the theoretical yield.
Ans → percent yield
Explanation →
Q. Name the process producing a mixture of lactic acid, ethanol and/or acetic acid, and CO2 as fermentation products
Ans → heterolactic fermentation
Explanation →
Q. a solution of definite pH made up in such a way that the pH alters only gradually with the addition of an acid or a base.
Ans → buffer solution
Explanation →
Q. The specific term used to describe carbohydrate stereoisomers differing only in configuration at the hemi-acetal carbon atom.
Ans → anomers
Explanation →
Q. A a substance which cannot be further subdivided by chemical methods.
Ans → element
Explanation →
Q. When a compound is changed into water, heat, and CO2 as a result of combining with oxygen.
Ans → combustion
Explanation →
Q. When a substance, called a solvent, is added to a suspension to reduce the concentration.
Ans → dilution
Explanation →
Q. The ability of electrons to "shuffle," or alternate, between bonds, making the molecule extremely stable. The best example of this is benzene.
Ans → Resonance
Explanation →
Q. A type of endocytosis in which extracellular ligands are targeted to specific cells through their binding to specific cell surface receptors
Ans → receptor-mediated endocytosis
Explanation →
Q. The deposit of a drug in a body created by injection or by a similar mode of introduction to form a source of slow release.
Ans → depot
Explanation →
Q. Name the class of antifungal drugs that inhibit ergosterol biosynthesis
Ans → imidazoles
Explanation →
Q. The carbohydrate that is taken as a reference for writing the configuration of others
Ans → Glyceraldehydes
Explanation →
Q. The sideways projection of a carbon-carbon single bond and the attached substituents.
Ans → sawhorse projection
Explanation →
