Pharmaceutical Organic Chemistry Questions

Practice topic-wise questions, MCQs, and one-liners selected by experts.

OLN

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.

OLN

It occurs when a hydrogen atom has an electromagnetic attractive interaction with an electronegative atom.

OLN

An organic molecule containing only hydrogen and carbon atoms.

OLN

An atom, or group of atoms, that is responsible for reactivity of the molecule it is a part of.

OLN

A molecule that seeks out electrons, also known as a Lewis Acid or an electron pair acceptor.

OLN

Electronegativity is a measure of the attraction an atom has for electrons.

OLN

A bond where four electrons are shared between two atoms.

OLN

The process by which proteins lose their 3-D (tertiary and secondary) structure by application of an external stress, most often heat.

OLN

The removal of water from a molecule.

OLN

A very strong attraction between two or more atoms that are sharing their electrons.

OLN

Isomers that differ in the order the atoms are placed. They have the same number of atoms, just in a different order.

OLN

An atom with four different atoms or groups attached to it.

OLN

a chemical reaction in which two species (e.g. molecules, ions or radicals) react together to form new chemical species.

OLN

the energy required to break a particular bond by a homolytic process.

OLN

any of two or more hypothetical structures of resonance theory which can be written for a molecule simply by rearranging the valence electrons of the molecule.

OLN

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.

OLN

the energy required to break a particular bond by a homolytic process.
