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. It occurs when a hydrogen atom has an electromagnetic attractive interaction with an electronegative atom.
Ans → Hydrogen Bonding
Explanation →
Q. An atom, or group of atoms, that is responsible for reactivity of the molecule it is a part of.
Ans → Functional Groups
Explanation →
Q. A hydrocarbon containing a carbonyl (C=O) adjacent to an ether (C-O-C) linkage.
Ans → Esters
Explanation →
Q. A molecule that seeks out electrons, also known as a Lewis Acid or an electron pair acceptor.
Ans → Electrophile
Explanation →
Q. Electronegativity is a measure of the attraction an atom has for electrons.
Ans → Electronegativity
Explanation →
Q. The process by which proteins lose their 3-D (tertiary and secondary) structure by application of an external stress, most often heat.
Ans → Denatured
Explanation →
Q. A very strong attraction between two or more atoms that are sharing their electrons.
Ans → Covalent Bond
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

Q. An equimolar mixture of the two enantiomeric isomers of a compound.
Ans → racemic mixture
Explanation →
Q. A conformation in which substituents on two attached saturated carbon atoms overlap when viewed as a Newman projection.
Ans → eclipsed
Explanation →
Q. Virus, therapeutic serum, toxin, antitoxin, or analogous product applicable to the prevention, treatment, or cure of diseases or injuries in humans and/or animals.
Ans → biological product

Q. The time it takes for a decaying radioactive substance to be reduced by half.
Ans → half–life
Explanation →
Q. A drug that dulls the sense of pain. It differs from an anesthetic agent in that it relieves pain without loss of consciousness.
Ans → Analgesic
Explanation →
Q. a substance that, when added to a reaction mixture, changes (speeds up) the rate of attainment of equilibrum in the system without itself undergoing a permanent chemical change.
Ans → catalyst
Explanation →
Q. An instrument used to measure the amount of rotation of plane polarized light by a compound, generally prepared in a solution
Ans → polarimeter
Explanation →
Q. When a substance, called a solvent, is added to a suspension to reduce the concentration.
Ans → dilution
