Organic Chemistry

Question 1

What is organic chemistry?

Answer 1

Study of compounds containing carbon

Question 2

What is a hydrocarbon?

Answer 2

Molecule containing hydrogen and carbon only

Question 3

What is a homologous series?

Answer 3

Families of organic compounds with the same functional group and general formula.

Question 4

What is covalent bond?

Answer 4

A chemical bond that involves sharing electrons between a pair of electrons

Question 5

What is the molecular formula?

Answer 5

Formula that gives the actual number of atoms of each element in that molecule

Question 6

What is the empirical formula?

Answer 6

Formula that gives the simplest ratio of atoms of each element in a compound

Question 7

What is the general formula?

Answer 7

Shows number of atoms of each element in a substance which has n carbon atoms. All the molecules in a homologous series have the same general formula

Question 8

What is the structural formula?

Answer 8

Shows how the atoms are joined together in a molecule

Question 9

What is the displayed formula?

Answer 9

Shows all the bonds and atoms in a molecule

Question 10

What is the skeletal formula?

Answer 10

Uses lines to represent bonds. Each point represents the C atoms. H atoms and bonds to H atoms are not usually shown. Other different ones are.

How many covalent bonds does carbon form?

Answer 11

4

Question 12

What does -ane tell you about the bond?

Answer 12

no double bond

Question 13

What does -ene tell you about the bonds?

Answer 13

Double bonds

Question 14

What are the names of the side chain prefixes?

Answer 14

• methyl - propyl - ethyl -butyl

Question 15

Name this compound.

Answer 15

2-methyl-butane

Question 16

What type of prefixes do ring moelcules have?

Answer 16

Cyclo

Question 17

What is a functional group?

Answer 17

An atom or group of atoms where when present in different molecules causes them to have similar chemical properties.

Question 18

What is a structural isomer?

Answer 18

Compunds with the same molecular formula different structures

Question 19

What is a chain isomer?

Answer 19

Compound with the same molecular formula but different structures of the carbon skeleton

Question 20

What is a position isomer?

Answer 20

Compunds with the same molecular formula but different structures due to different positions of the same functional group on the same carbon skeleton

Question 21

What is a functional group isomer?

Answer 21

Compound with the same moelcular formula but with atoms arranged to give different functional groups.

Question 22

Name this compound.

Answer 22

1-dichloro- ethane

Question 23

What is the general formula of an alkane?

Answer 23

CnH2n+2

What is the general formula of an alkene?

Answer 24

CnH2n

Question 25

Name this compound.

Answer 25

But-1-ene

Question 26

What are stereoisomers?

Answer 26

They have the same structural formulae but have a different spatial arrangement of atoms.

Question 27

When do E-S stereoisomers arise?

Answer 27

Restricted rotation around the c=c double bond

Two different groups/atoms attached both ends of the double bond

Question 28

What is the priority group?

Answer 28

Atom with the bigger atomic number.

Question 29

Draw what E-Z isomerism is.
