Question
Classify each of the following hydrocarbon structural formulas as an alkane, cycloalkane, alkene, alkyne, or aromatic hydrocarbon.
(A)
alkane or cycloalkane or alkene or alkyne or aromatic
(B)
alkane or cycloalkane or alkene or alkyne or aromatic
(C)
alkane or cycloalkane or alkene or alkyne or aromatic
(D)
alkane or cycloalkane or alkene or alkyne or aromatic
(E)
alkane or cycloalkane or alkene or alkyne or aromatic
Explanation / Answer
a) This structure has a double bond, and no other structure in the list has a double bond, thus this must be an ALKENE (ene is for double bonds) b) This structure has a ring but it has neither any double bonds nor triple bonds, thus its is a CYCLOALKANE (cyclo for ring and alkane because no double or triple bonds) c) This structure has no ring, no double bonds and only a triple bond hence it is an ALKYNE (the yne is for triply bonded compounds) d) This structure has no double bonds, no triple bonds and no rings, thus only possible name would be that it is an ALKANE e) This structure has a ring and has double bonds and it also confirms the 4n+2 rule for aromaticity, thus it is an AROMATIC ring
