Organic

Question 1

Molecular Formula

Answer 1

A chemical formula that indicates the type of elements and number of each of the atoms in a molecule.

Question 2

Structural formula

Answer 2

Indicates which atoms are attached to which in a molecule. Atoms are represented by their chemical symbols and lines are used to represent all the bonds that hold the atom together.

Question 3

Condensed Structural Formula

Answer 3

Shows way in which atoms are bonded together in a molecule, but does not show all bond lines.

Question 4

Hydrocarbon

Answer 4

An organic molecule consisting of hydrogen and carbon only

Question 5

Homo series

Answer 5

A series of organic compounds that can be described by the same general formula

Question 6

Unsaturated

Answer 6

Compounds with 1 or more double bonds between c atoms in their hydrocarbon chain.

Question 7

Functional group

Answer 7

A bond or an atom or a group of atoms that determine the physical properties of a compound

Question 8

Structural Isomer

Answer 8

Organic molecules with the same molecular formulae, but different structural formulae.

Question 9

Chain Isomer

Answer 9

Same molecular formula, but different chains

Question 10

Positional isomer

Answer 10

Same molecular formulae, but different positions of the side chain, substituents or functional groups on the parent chain

Question 11

Functional Isomer

Answer 11

Same molecular formulae, but different functional groups.
