1. sp 3 ; it is a σ bond that is cylindrically symmetrical (all cross sections perpendicular to the internuclear axis are<br />

circles).<br />

2.<br />

3. The sp 3 hybridized orbitals form bonds at tetrahedral angles (109.5°), which forces the carbon atoms to form<br />

a zigzag chain.<br />

1. Single bonds between carbon atoms are free to rotate 360°.<br />

a. Explain what happens to the potential energy of an n-hexane molecule as rotation occurs<br />

around the C2–C3 bond.<br />

b. Draw Newman projections of the n-hexane conformations corresponding to the energy minima <strong>and</strong> maxima<br />

in the diagram, which shows potential energy versus degrees of rotation about the C3–C4 axis.<br />

the structural isomers of each compound.<br />
