Complete the following table:

$11.$ a$)$ Draw the Lewis structure for ammonia $($NH$3).$ Be sure to include any lone pairs.

b$)$ Draw a VSEPR diagram for ammonia. What is the name for this arrangement of bonds?

c$)$ Compared to methane $($see question $10$ above$)$ are the bonds in ammonia closer together or

further apart? What is the reason for this?

d$)$ Between ammonia and methane, which has stronger intermolecular forces? Why is this?

e$)$ What does it mean for an ammonia molecule to form a coordinate bond? What is the result

if it forms a coordinate bond with an H$+$ ion? $($Hint: there is a table of polyatomic ions on page $6)$

$12.$ a$)$ Draw a VSEPR diagram for acetic acid $($CH$3$COOH$).$ Identify the three different shapes $($i$.$e$.,$

arrangements of bonds$/$lone pairs$)$ that are present.

b$)$ Explain why acetic acid is soluble in water. Your answer should make reference to

electronegativity differences between atoms and the shapes of the molecules.
