Identify the type of hydrocarbons or its functional group.

Question

Directions: Identify the type of hydrocarbons or its functional group.

1. C6H10 6. CH3CH2CH2CH2OH

2. C8H18 7. CH3CH2CH2CH2CH2CH3

3. C4H8 8. H2NCCH3

4. C20H42 9. CH3C-O-CH2CH2CH3

5. C7H14 10. CH3CH2CH2CH3

Answer 1

Assuming no typo,

1 H nuumber=2n-2 (n is C number), it is cyclohexene or Hexyne. Double bond or triple bond is functional

2, 4, 7&10 H number=2n+2 (n is C number), so they are saturated alkanes, no functional groups

3&5, H number=2n (n is C number), they are alkenes or cycloalkanes, double bonds are functional groups in alkenes

6 alcohol, OH is the functional group

8 assuming it H2NCH2CH3, amine, NH2 is a functional group

9 ether
