A college is an educational institution or a constituent part of one. A college may be a degree-awarding tertiary educational institution, a part of a collegiate or federal university, an institution offering vocational education, a further education institution, or a secondary school.
A community college is a type of undergraduate higher education institution, generally leading to an associate degree, certificate, or diploma. The term can have different meanings in different countries: many community colleges have an "open enrollment" for students who have graduated from high school. The term usually refers to a higher educational institution that provides workforce education and college transfer academic programs. Some institutions maintain athletic teams and dormitories similar to their university counterparts.
A school is both the educational institution and building designed to provide learning spaces and learning environments for the teaching of students under the direction of teachers. Most countries have systems of formal education, which is sometimes compulsory. In these systems, students progress through a series of schools that can be built and operated by both government and private organization. The names for these schools vary by country but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught is commonly called a university college or university.
In organic chemistry, the Diels–Alder reaction is a chemical reaction between a conjugated diene and a substituted alkene, commonly termed the dienophile, to form a substituted cyclohexene derivative. It is the prototypical example of a pericyclic reaction with a concerted mechanism. More specifically, it is classified as a thermally-allowed [4+2] cycloaddition with Woodward–Hoffmann symbol [π4s + π2s]. It was first described by Otto Diels and Kurt Alder in 1928. For the discovery of this reaction, they were awarded the Nobel Prize in Chemistry in 1950. Through the simultaneous construction of two new carbon–carbon bonds, the Diels–Alder reaction provides a reliable way to form six-membered rings with good control over the regio- and stereochemical outcomes. Consequently, it has served as a powerful and widely applied tool for the introduction of chemical complexity in the synthesis of natural products and new materials. The underlying concept has also been applied to π-systems involving heteroatoms, such as carbonyls and imines, which furnish the corresponding heterocycles; this variant is known as the hetero-Diels–Alder reaction. The reaction has also been generalized to other ring sizes, although none of these generalizations have matched the formation of six-membered rings in terms of scope or versatility. Because of the negative values of ΔH° and ΔS° for a typical Diels–Alder reaction, the microscopic reverse of a Diels–Alder reaction becomes favorable at high temperatures, although this is of synthetic importance for only a limited range of Diels-Alder adducts, generally with some special structural features; this reverse reaction is known as the retro-Diels–Alder reaction.

A junior college is a post-secondary educational institution offering vocational training designed to prepare students for either skilled trades and technical occupations and support roles in professions such as engineering, accountancy, business administration, nursing, medicine, architecture, and criminology, or for additional education at another college with more advanced academic material. Students typically attend junior colleges for one to three years.
A secondary school or high school is an institution that provides secondary education and also usually includes the building where this takes place. Some secondary schools provide both lower secondary education and upper secondary education, i.e., both levels 2 and 3 of the ISCED scale, but these can also be provided in separate schools.
