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 →

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

Q. Substrate level phosphorylation in citric acid cycle is catalysed by the enzyme
Ans → Succinate thiokinase
Explanation →
Q. Isomers that differ in the order the atoms are placed. They have the same number of atoms, just in a different order.
Ans → Constitutional Isomers
Explanation →
Q. A process in which the forward reaction can reach an equilibrium with the reverse reaction.
Ans → reversible process
Explanation →
Q. Part of the orbital area in an atom where it is impossible to find an electron.
Ans → node

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 energy levels of electrons in an atom which may be described in terms of the four quantum numbers.
Ans → atomic orbital
Explanation →

Q. A solution property that changes if the concentration of that solution changes.
Ans → colligative property
Explanation →
Q. Technique that uses living organisms to make or modify products, to improve plants or animals, or to develop microorganisms for specific uses
Ans → biotechnology
Explanation →
Q. Technique in which antibody or antigen can be concentrated by passing fluids through porous membranes, and target molecules are captured as they pass
Ans → immunofiltration
Explanation →
Q. An instrument used to measure the amount of rotation of plane polarized light by a compound, generally prepared in a solution
