Concept explainers
(a)
Interpretation:
The “complex” five-carbon branched alkyl group has to be named using IUPAC rules.
Concept Introduction:
Alkyl groups are named according to
Rule 1:
Longest continuous chain which begins at the point of attachment of the alkyl group becomes the base name for the alkyl group.
Rule 2:
Base chain that is identified is numbered in a way beginning at the point of attachment.
Rule 3:
The substituents that are present in the base chain are listed in alphabetical order using the locant as prefixes whenever necessary.
(b)
Interpretation:
The “complex” five-carbon branched alkyl group has to be named using IUPAC rules.
Concept Introduction:
Alkyl groups are named according to IUPAC nomenclature. The name is obtained considering the parent alkane name and replacing “-ane” with “-yl”. In naming branched chain alkyl groups, this becomes little complicated. Hence, IUPAC system for giving name to such larger groups names them by considering as if they were themselves a separate compound. Three rules are followed while naming the larger groups.
Rule 1:
Longest continuous chain which begins at the point of attachment of the alkyl group becomes the base name for the alkyl group.
Rule 2:
Base chain that is identified is numbered in a way beginning at the point of attachment.
Rule 3:
The substituents that are present in the base chain are listed in alphabetical order using the locant as prefixes whenever necessary.

- A pdf file of your hand drawn, stepwise mechanisms for the reactions. For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.
