Are the structures below polar or nonpolar? Circle the polar ones. Explain why the are polar and indicate the direction of all polar bonds.

Clear my choice For the series methane, ammonia, and water, the bond angle increases in the following order: H,0 < NH3 < CH4. This trend is due to Select one: O a. a decreasing effective nuclear charge. O b. a decrease in the number of lone pairs. O c. an increase in atomic radius. d. an increase in the polarity of the molecules. O e. an increasing effective nuclear charge. Which bond angle is the largest? Select one: a. O-C-Sin COS

In an alternate universe, these are types of electron cloud shapes a D cloud (shape in blue), and a E cloud (shape in gray). The nucleus is represented by a green circle. All other rules about orbitals and types of bonding are the same as our universe. A В E (one on top of the other) Answer the following questions below in Canvas A. Which orientation of clouds do you think would create the strongest bond and why B. Which orientation of clouds do you think represents a sigma bond and why C. Which orientation of clouds do you think represents a pi bond and why make sure you label which question you are answering
