Answer:

Common types of reaction

Substitution: Replace sigma bond with another sigma bond. Elimination: Break two sigma bonds and form a new pi bond. Addition: Break a pi bond and form two new sigma bonds.

Answer:

Substitution reactions, elimination reactions, and addition reactions are types of organic reactions that occur when organic compounds undergo chemical changes.

1-Substitution reactions: involve the replacement of an atom or a group of atoms in a molecule with another atom or group of atoms.

2-Elimination reactions: involve the removal of a molecule or a group of atoms from a larger molecule to form a smaller molecule.

3-Addition reactions: involve the addition of one or more atoms or groups of atoms to a molecule to form a larger molecule.

Step-by-step explanation:

Substitution, elimination, and addition reactions are types of organic reactions that occur when one or more chemical compounds react to form new compounds.

A substitution reaction occurs when one functional group is replaced by another functional group in a molecule. For example, when an alkane reacts with a halogen, such as chlorine, a substitution reaction occurs where the halogen replaces one of the hydrogen atoms in the alkane molecule.

An elimination reaction occurs when a molecule loses a small molecule, such as water, to form a new compound. For example, when an alcohol is heated with a strong acid, an elimination reaction occurs where the alcohol loses a water molecule to form an alkene.

An addition reaction occurs when a molecule adds to a double or triple bond to form a new compound. For example, when an alkene reacts with hydrogen gas in the presence of a catalyst, an addition reaction occurs where the hydrogen atoms are added to the double bond to form an alkane.
