In each pair of atoms, which has the larger atomic radius? Which is more electronegative?
(b) C vs. O

Rank the following elements from least electronegative to most electronegative.

Na, Si, F, Mg, C, O, N

(i) Using the periodic trend, choose the more electronegative atom in each pair. For one pair, you'll need to look at the actual Pauling values. (ii) For which one? (iii) Why?

(b) N vs. O

(i) Using the periodic trend, choose the more electronegative atom in each pair. For one pair, you'll need to look at the actual Pauling values. (ii) For which one? (iii) Why?

(d) B vs. Si

In each pair of atoms, which has the larger atomic radius? Which is more electronegative?

(c) O vs. S

Which bond is stronger? Briefly explain why.

b.

Which bond is stronger? Briefly explain why.

a.

For each pair of compounds, predict which one has the higher molecular dipole moment, and explain your reasoning.

a. ethyl chloride or ethyl iodide

b. 1-bromopropane or cyclopropane

For each alkene, indicate the direction of the dipole moment. For each pair, determine which compound has the larger dipole moment.

a. cis-1,2-difluoroethene or trans-1,2-difluoroethene
