Polar and Polarity III

Polar and Polarity III

Preamble: There is the age old saying oil does not mix with water. The reason behind this is because polar does not mix with non-polar. To take it deeper, molecules mix well with other molecules with similar IMF’s.

Narrator: Welcome to the third installment of Polar and Polarity. In a world where one’s status is determined by ones polarity. The more polar the more desirable. In our last episode, Kate, a C5H12 molecule was in love with Henry, a C2H6O molecule with hydrogen bonds. Henry’s father, Sir Charles, a C2H4O2molecule, wished him to marry Alice, a C3H8O molecule with hydrogen bonds. Edward, Henry’s friend, another C2H6O, molecule with no hydrogen bonds, is partial to Kate’s cousin Sarah, a C4H8O2 molecule with many suitors due to her hydrogen bonds. Henry acquiesces to his father’s wishes and Edward declares his love for Katherine after being cast aside by Sarah for the dashing Geoffrey a C4H10O with hydrogen bonds. Our scene opens with Edward and Sarah married with a son William, a C4H10O, who has not settled on whom to marry. William is an especially handsome young man with hydrogen bonding capabilities.

Edward: Son, your mother and I are quite anxious to discover which young lady you have settled on to marry.

William: Dear father and mother I have not yet found a young lady to whom I am willing to devote my life.

Edward: Son, find a girl who is pleasing to your eyes, and from a good lineage. The rest will work itself out. What about Belle? She is a very handsome C3H6O2 molecule, with hydrogen bonds.

William: Father, she is a lovely girl, but not for me.

Katherine: My dear husband, matters of the heart are not to be taken lightly.

William: I only want to be in love like you and mother.

Katherine: It took me a little while to be sure of your father’s love for me, and mine for him. After all we were both spurned by our other lovers. But I am quite assured of his affection for me and mine for his. (Katherine and Edward hold hands.)

Edward: It is my express wish that you are married and settled by this time next year. You have to think of producing heirs dear William. (Edward leaves)

William: I shall never understand father. He is determined to make my life miserable. I wanted to study medicine, he opposed. I wanted to travel to the continent and study art, he opposed. He wants me to be like him, and I am not.

Katherine: My dear sweet child. Your father loves you very much, but he is a man, and has much to think about. Tell your mama, is there not a girl whom you prefer?

William: I confess I do mother.

Katherine: I had my suspicions. Pray, who is she?

William: I am afraid to say. Father will not approve. It is Jane…Yes I know she is a C8H18 molecule.

Katherine: Ahh…Jane. I see. Do you love her?

William: Yes mother, with all my heart. Mother, even though you are not polar, and dad is, you both have non polar parts in common.

Katherine: Yes but Edward—your father desires you to form stronger connections that will secure your future.

Narrator: The characters are assembled at a ball. Belle and William are talking on one side of the room, while Jane and her Friend Mallory, a C6H12 molecule are also engaged in conversation. Henry and his wife Alice are present likewise Edward and Katherine.

Mallory: You cannot be serious! William proposed to you yesterday?

Jane: Shh. Pray lower your voice! His parents know not of our engagement.

Mallory: Shocking indeed! Why is he then still enjoying Belle’s company?

Jane: Oh dear! I cannot bear artifice. I cannot pretend any longer when we are in public.

Belle: William, you have not said two words together this whole hour. You seem terribly dull this evening.

William: I am a bit tired from travelling on yesterday. That is all. Shall we not dance?

Narrator: The couples then proceed to dance. (Pause for dancing). Afterwards Jane approaches William)

Jane: William, I must speak to you.

Belle: William, is she not the daughter of your governess?

William: Ah, yes—Jane, could we speak later, please?

Jane: No William. I will not be put off any longer.

William: Pray excuse me Belle.

(They move to one side of the room)

Jane: Either you will publicly declare your love for me, or I will have nothing to do with you.

William: Jane, I love you so ardently. I just need time to tell my parents.

Jane: Take all the time you need sir. I will not be trifled with in this way.

Narrator: Jane, in tears, leaves the ball with Mallory. William starts to go after her, but is impeded by Edward.

Edward: My son, are you to tell me Jane, the daughter of your former governess is the one whom you are fixed upon to marry?

William: Yes sir. I love her.

Edward: I cannot permit it. Jane has no family name, no fortune….

William: Neither did mother…

(Edward strikes William)

Edward: How dare you speak that way about your mother!

(Katherine rushes over)

William: You sir are a hypocrite.

(Edward makes to strike him again. Katherine holds his hand)

Katherine: Both of you have lost all sense of decorum. I am ashamed of both of you. Please compose yourselves before you expose us to more shame.

Edward: If you marry her, you will be penniless.

William: Then I will make my own way in the world.

Katherine: Edward if you disown your only son, I will leave you. Then you have a bigger scandal on your hands. I will not let you mistreat your son in this way.

Edward: Oh you will leave me and receive Henry’s affections. I know you have been corresponding for years. And I also know William is his son. Now there’s a scandal for you, eh William?

(Edward walks out)

Narrator: Oh dear. What will happen to our characters? How did Edward uncover Henry’s and Katherine’s secret? Will Edward’s and Katherine union be dissolved due to this scandalous affair? Will William marry Jane? Is Henry truly his father? Join us next time for Polar and Polarity.
