functional groups

Question 1

NH2

Question 2

Answer 2

single bond

Question 3

carboxylic acid functional group

Answer 3

OOH (don’t number)

Question 4

alcohol functional group

Answer 4

OH

Question 5

alkyne functional group

Answer 5

triple bond

Question 6

haloalkane functional group

Answer 6

halides - bromine, chlorine, iodine, fluorine

Question 7

requirements for a cis-trans isomer

Answer 7

• can only occur due to carbon=carbon double bonds not rotating
• each carbon on the double bond must have two different groups attached

Cis isomers have the same groups on the same side of the molecule whereas trans are on opposite sides —> different physical properties but the same chemical
- same molecular and sequence of atoms but different arrangements in space (3D)

Question 8

constitutional isomer

Answer 8

A constitutional (structural) isomer has the same molecular formula, but a different arrangement of atoms / different structural formula.
