Chapter 2 HW Problem Set Assigned Chapter 2 Textbook Problems (very important for problem practice): 7 th^ edition: 29 - 36, 37a-g, 38-41, 43-44, 48, 54, 56, 57 8 th^ edition: 34, 36-41, 44, 45a-g, 46-49, 51-52, 56, 62, 64, 65
Use all the assigned textbook problems above for practice. On this HW, show your work for
five individual problems that you consider representative from the assigned textbook
problems. (e.g. 45b counts as one problem). Insert a blank page if more space is needed.
Q1: Curved Arrows, Bronsted Acids & Bases, Lewis Acids & Bases Considering the following reactions:
a) Predict the products to complete the reactions.
b) Use curved electron-pushing arrows to show the mechanism for the reaction in
the forward direction. Redraw some of the compounds to explicitly illustrate all
bonds that are broken and all bonds that are formed.
c) Label Bronsted acids and bases in the left side of the reactions. Label conjugate
acids and bases in the right side of the reactions.
d) Label Lewis acids and bases, nucleophiles and electrophiles in the left side of the
reactions.

Q 4 : Naming the Alkanes a) Write the IUPAC nomenclature of the compound below b) Draw 4 - isopropyl-2,4,5-trimethylheptane, identify the primary, secondary, tertiary, and quaternary carbons. c) Rank pentane, neopentane and isopentane for boiling point. Q5: Conformations of Alkanes a) Draw a Newman Projection of the compound below about the C2-C3 bond.
b) Translate the Newman projection below to its wedge-and-dash drawing. c) Isopentane ( 2 - methylbutane) is a compound containing a branched carbon chain. Draw a Newman projection of six conformations about the C2-C3 bond of isopentane. On the curve of potential energy versus angle of internal rotation for isopentane, label each energy maximum and minimum with one of the conformations.
