Flashcards in Organic Definitions Deck (28):
1

What is a addition reaction?

A reaction where a molecule joins to an unsaturated molecule to produce a saturated molecule.

2

What is an aliphatic?

An organic compound containing C chains and branches.

3

What does aromatic mean?

An organic compound containing one or more benzene ring(s).

4

What is a carbocation?

A positive ion with the positive charge on a C atom.

5

What does cyclic mean?

An organic compound containing C rings (not aromatic rings)

6

What is dehydration?

The elimination of water.

7

What is dehydrogenation?

The elimination of hydrogen.

8

What is an electrophile?

An electron deficient molecule/lone pair acceptor.

9

What is an elimination reaction?

A reaction where a molecule is lost from a saturated molecule to form an unsaturated molecule.

10

What is a free radical?

A species with an unpaired electron.

11

What is a functional group?

The atom or group of atoms that is responsible for most of the chemical reactions of a molecule.

12

What is an homologous series?

A family of compounds with the same general formals and similar chemical properties.
In a series, each member differs by the addition of a CH2 group and there is a gradual change in physical properties.

13

What is hydration?

The addition of water.

14

What is a hydrocarbon?

A molecule containing hydrogen and carbon only.

15

What is hydrogenation?

The addition of hydrogen.

16

What is hydrolysis?

A reaction involving the breaking of bonds due to the addition of a water molecule.

17

What is a nucleophile?

An electron rich species / a lone pair donator.

18

What is organic chemistry?

The study of carbon containing compounds.

19

What does saturated mean?

A molecule containing no double bonds.

20

What are stereoisomers?

Molecules with the same molecular and structural formulae but with a different spatial arrangement of atoms. (Atoms arranged differently in space)

21

What are geometric isomers?

A type of stereoisomers;
Molecules that have a different arrangement of groups around C=C.

22

What are optical isomers?

A type of stereoisomers;
Molecules which are non-superimposable mirror images.

23

What are structural isomers?

Molecules with the same molecular formulas but with a different arrangement of atoms.

24

What are chain isomers?

A type of structural isomer;
They differ by having a different carbon chain.

25

What are position isomers?

A type of structural isomer;
They different by having the functional group in a different position.

26

What are functional group isomers?

A type of structural isomer;
They different by having a different functional group.

27

What is a substitution reaction?

A reaction where an atom/group replaced another atom/group.

28

What does unsaturated mean?

A molecule containing double bonds.
