What are the names of the following three compounds (see attached)
balu736 [363]

Answer:

1. 4-ethyl-1-heptene

2. 6-ethyl-2-octene

3. 1-butyne

Explanation:

The compounds are named according to IUPAC rules.

Compound 1:

  • Identify the longest carbon chain. This chain is called the parent chain.
  • Identify all of the substituents (groups appending from the parent chain).
  • The parent chain is numbered so that the multiple bonds have the lowest numbers (double has the priority over alkyl substituents).
  • The longest chain contains 7 carbon atoms, so taken the name hept.
  • The double bond between C1 and C2, so take no. 1 and add the suffix ene to hept "1-heptene".
  • The ethyl group is the alkyl substituent on position 4.
  • So the name is 4-ethyl-1-heptene.

Compound 2:

  • Identify the longest carbon chain. This chain is called the parent chain.
  • Identify all of the substituents (groups appending from the parent chain).
  • The parent chain is numbered so that the multiple bonds have the lowest numbers (double has the priority over alkyl substituents).
  • The longest chain contains 8 carbon atoms, so taken the name oct.
  • The double bond between C2 and C3, so take no. 2 and add the suffix ene to oct "2-octene".
  • The ethyl group is the alkyl substituent on position 6.
  • So the name is 6-ethyl-2-octene.

Compound 3:

  • Identify the longest carbon chain. This chain is called the parent chain.
  • Identify all of the substituents (groups appending from the parent chain), there is no substituents.
  • The parent chain is numbered so that the multiple bonds have the lowest numbers (Triple bond here take the lowest number).
  • The longest chain contains 4 carbon atoms, so taken the name but.
  • The triple bond between C1 and C2, so take no. 1 and add the suffix yne to but "1-butyne".
  • So the name is 1-butyne.
