Introduction To Organic Chemistry

Question 1

What is the general formula?

Answer 1

Algebraic formula describing any member of a homologous series

Question 2

What is the empirical formula?

Answer 2

Simplest ratio of atoms in a compound

Question 3

What is the molecular formula?

Answer 3

Actual number of atoms in a molecule

Question 4

What is the structural formula?

Answer 4

Shows the structure of atoms in a molecule

Question 5

What is the skeletal formula?

Answer 5

Shows bonds between carbon skeleton only

Question 6

Define homologous series

Answer 6

group of compounds containing the same functional group, represented by the same general formula

Question 7

What does a curly arrow show?

Answer 7

Movement of a pair of electrons during a reaction

Question 8

What is an isomer in general?

Answer 8

Molecules with the same molecular formula but different arrangement of atoms

Question 9

define Chain isomers

Answer 9

Molecules with same molecular formula but one is branched and the other is linear e.g. Butane and Methylpropane

Question 10

define Positional isomers

Answer 10

Molecules with the same molecular formula but a difference in position of the functional group e.g. 1-chlorobutane and 2-chlorobutane

Question 11

define Functional group isomers

Answer 11

Molecules with the same molecular formula but atoms are arranged into different functional groups e.g. Hex-1-ene and cyclohexane

Question 12

What is stereoisomerism?

Answer 12

Molecules with the same structural formula but different arrangement in space. Happens due to restricted rotation about the C=C double bond

Question 13

Z isomer

Answer 13

Same groups on same side

Question 14

E isomer

Answer 14

Groups on opposite sides
