CHEM 201—Functional Groups

Questão	Responda
Functional Groups	Recognized collections of atoms with the same structure which implies they have the same properties. Have known reactivity
Carboxylic Acid	Has a COOH group and has acid properties but can be attached to another molecule
Carboxylic Acid Family	Includes carbonyl groups, acid chlorides, acid hydrides, esters, and amides
Carbonyl Group	Is a carbon double-bonded to an oxygen that has two lone pairs
Acid Chlorides	Have a carbonyl group connected to a chloride
Acid Hydrides	Have a carbonyl group that is bonded to an oxygen which is bonded to another carbonyl group
Ester	A carbonyl group that is bonded to an oxygen which is bonded to a carbon that is bonded to other things
Amide	A carbonyl group that is bonded to a nitrogen
Carbonyl Family	Includes ketones, aldehydes, and formaldehydes
Ketone	A carbonyl group bonded to two carbons from the central carbon
Aldehyde	A carbonyl group bonded to a carbon and a hydrogen
Formaldehyde	A carbonyl group bonded to two hydrogens from the central carbon
Alcohol Family	Includes ethers and amines
Ether	An oxygen with two lone pairs bonded to a carbon on either side which can be bonded to other things
Amine	A nitrogen with two lone pairs that is bonded to three other things
Polarity	The carboxylic acid family will be polar because of the carbonyl dipole on the edge of the molecule, and the alcohol family will be non-polar because more than one dipole is pointing inward
Constitutional Isomers	When a something has the same molecular formula but different connectivity
