Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
In India, the 11th Grade is the first year of higher secondary education and is often considered the third year of high school (Higher/Senior Secondary School or Senior High School). It is commonly known as "Class 11" or "Plus 1" (derived from "10+1") and, in some states, as the first year of Junior College (Intermediate or Pre-University Course).

Stereochemistry, a subdiscipline of chemistry, studies the spatial arrangement of atoms that form the structure of molecules and their manipulation. [1] The study of stereochemistry focuses on the relationships between stereoisomers, which are defined as having the same molecular formula and sequence of bonded atoms (constitution) but differing in the geometric positioning of the atoms in space.
In organic chemistry, a cross-coupling reaction is a reaction where two different fragments are joined. Cross-couplings are a subset of the more general coupling reactions. Often cross-coupling reactions require metal catalysts. One important reaction type is this:
The College of William and Mary uses 5 digits for course reference numbers (CRNs). The CRN's first digit is 2 for a spring class, 3 for a summer class, and 1 for a fall class. Sometimes the same course is taught by different faculty and/or at different times. In this case, a section number is used to differentiate between the different classes. [9]
