redox 1

Question 1

Define the structural formula

Answer 1

Shows the minimal detail that shows the arrangement of atoms in a molecule.

Question 2

Define The displayed formula

Answer 2

Shows all the covalent bonds in a molecule

Question 3

Define the skeletal formula

Answer 3

Shows the simplified organic formula, shown by removing hydrogen atoms from alkyl chains and just leaves the associated functional groups.

Question 4

What is the functional group of alkanes and alkenes?

Answer 4

Alkanes: C-C
Alkenes: C=C

Question 5

What is the functional group for alcohols and halogenoalkanes

Answer 5

Alcohols: OH
Halogenoalkanes: C-Halogen

Question 6

What is the functional group for aldehydes and their suffix?

Answer 6

• C=O to a H AT THE END
• -al
• eg: Propanal

Question 7

What is the functional group for ketones?

Answer 7

• C=O in the middle of a molecule
• one
• eg: Propanone

Question 8

What is the functional group for carboxylic acids and esters?

Answer 8

• COOH
• C=O-O

Question 9

What is the suffix and functional group for Amines?

Answer 9

• NH3
• Amine

Question 10

define stereoisomers

Answer 10

Have the same structural formulae but have a different special arrangement of atoms.

Question 11

What are reasons for E-Z isomers arising?

Answer 11

• when there’s restricted rotation around the C=C bond
• There are 2 different groups or atoms attached both ends of the double bond

Question 12

What is a priority group?

Answer 12

• the atom with the larger atomic number.

Question 13

How do you name E-Z isomers?

Answer 13

• If the priority group is on the same place on either side of the C=C bond, it is named a Z isomer
• But if on the opposite side of the double bond, then it’s labelled an E isomer

Question 14

What is cis-trans isomerism?

Answer 14

• when special case of EZ isomerism in which subsequent groups are the same.
