3. H—Cl or H—F

Which type of bond is formed by the sideways overlap of $p$ orbitals in the conjugated portion of a molecule?

a. Which bond would be longer?

b. Which bond would be stronger?

2. C—C or C—Cl

For the following partial structures, the bond is shown. Add the indicated number of bonds, being sure to specify the orientation (that is, x, y, or z axis) of the p orbitals used.

(c)

Which of the bonds in a carbon–oxygen double bond has more effective orbital–orbital overlap: the σ bond or the π bond?

Given the Lewis structures, indicate the direction of the dipole moment, if there is one.

(e)

a. Which bond would be longer?

b. Which bond would be stronger?

1. C—Cl or C—I

How many s bond orbitals are available for overlap with the vacant p orbital in the methyl cation?
