Concept explainers
(a)
Interpretation: Primary, secondary and tertiary hydrogen in structure of ethane should be labeled.
Concept introduction: In accordance with IUPAC convention longest chain can be found from either direction provided it is longest and digits indicate the position of carbon or the position of branched alkyl chain in cases of branched hydrocarbons. All the side chains are named in alphabetical order.
The IUPAC system for nomenclature of straight hydrocarbon makes use of table given as follows:
Beside the IUPAC names there are certain common names. The common prefixes used include prefixes “iso-” and “neo-”.For example, isobutane is common name used popularly for
The carbon linked to one alkyl/carbon while other two
The carbon linked to two alkyl /carbons and one
The carbon linked to three alkyl groups/carbons and no
These are indicated below:
(b)
Interpretation: Primary, secondary and tertiary hydrogen in structure of pentane should be labeled.
Concept introduction: In accordance with IUPAC convention longest chain can be found from either direction provided it is longest and digits indicate the position of carbon or the position of branched alkyl chain in cases of branched hydrocarbons. All the side chains are named in alphabetical order.
