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 →

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
