Concept explainers
(a)
Interpretation:
The structure corresponding to 4-methyl-1-hexene should be given.
Concept Introduction:
(b)
Interpretation:
The structure corresponding to 5-ethyl-2-methyl-2-heptene should be given.
Concept Introduction:
Alkenes are named in the same way as alkanes, but the alkenes are identified by the suffix −ene, replaced instead of the ending of the name of the parent alkane. The longest carbon chain should be numbered in a way that gives the double bond the lower number. Then the compound should be named using the first number assigned to the double bond. The names of the substituents should be written first in the alphabetic order with their position on the chain.
(c)
Interpretation:
The structure corresponding to 2,5-dimethyl-3-hexyne should be given.
Concept Introduction:
(d)
Interpretation:
The structure corresponding to 1-propylcyclobutene should be given.
Concept Introduction:
In the nomenclature of cycloalkenes, the double bond is always located between C-1 and C-2. And 1 is not mentioned in the name. The ring is then numbered in a way that the first substituent gets the lowest number.
(e)
Interpretation:
The structure corresponding to 1,3-cyclohexadiene should be given.
Concept Introduction:
In the nomenclature of cycloalkenes, the double bond is always located between C-1 and C-2. And 1 is not mentioned in the name. the ring is then numbered in a way that the first substituent getting the lowest number.
(f)
Interpretation:
The structure corresponding to 4-ethyl-1-decyne should be given.
Concept Introduction:
Alkynes are named in the same way as alkanes, but the alkynes are identified by the suffix −yne, replaced instead of the ending of the name of the parent alkane. The longest carbon chain should be numbered in a way that gives the triple bond the lower number. Then the compound should be named using the first number assigned to the triple bond. The names of the substituents should be written first in the alphabetic order with their position on the chain.
