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

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

Q. An aromatic molecule or ion possesses aromaticity. Aromaticity is the special property of planar (or nearly planar) cyclic, conjugated systems having (4n+2) conjugated pi electrons.
Ans → aromatic
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. Name the highly branched storage polysaccharide that is found animal cells and bacteria
Ans → glycogen
Explanation →
Q. Name the amino acid that directly participates in the synthesis of heme
Ans → Glycine
Explanation →
Q. Name a property, which serves as basis for the process whereby surfactants are used for the removal of foreign matter from surfaces (including dirt from clothes or body surfaces).
Ans → detergency
Explanation →
Q. the method for producing gasoline from heavy petroleum distillates.
Ans → catalytic cracking
Explanation →
Q. Repair of the sugar-phosphate backbone of the DNA, making the DNA molecule continuous
Ans → ligation
