Artemisinin, as pure substance has a slightly polar character.
The cause is the polar character of water molecule.
PVA, or polyvinyl alcohol, is polar due to its hydroxyl (-OH) groups, which are capable of forming hydrogen bonds with water and other polar substances. These hydroxyl groups create regions of partial positive and negative charges, contributing to the molecule's overall polar character. The presence of these polar functional groups enhances PVA's solubility in water and its compatibility with other polar materials.
Not all compounds with polar bonds are polar because the overall polarity of a molecule depends on its molecular geometry. If the polar bonds are arranged symmetrically, their dipole moments can cancel each other out, resulting in a nonpolar molecule. For example, carbon dioxide (CO₂) has polar bonds, but its linear shape leads to a nonpolar character. Conversely, if the shape is asymmetrical, the molecule can exhibit a net dipole moment and be polar.
SiO3^2- (silicate ion) is considered to be polar due to its geometric structure and the presence of polar bonds between silicon and oxygen atoms. The arrangement of the oxygen atoms around the silicon atom leads to an unequal distribution of electron density, resulting in a dipole moment. Consequently, the overall molecular geometry contributes to its polar character.
Covalent bonds have ionic "character" when they are polar. The more polar, (greater the electronegativity difference) the more ionic character.

The main character and protagonist in "The Polar Express" is known simply as "the boy" or "the Hero Boy." He is the central character who embarks on a magical journey to the North Pole.
NF3 is a polar covalent molecule. While the electronegativity difference between N and F suggests more ionic character, the shape of the molecule (trigonal pyramidal) results in an uneven distribution of charge, making it polar covalent.

In "The Polar Express," Tom Hanks voices several characters, including the Conductor, the Hero Boy, and Santa Claus. However, he does not portray the character of the Hero Girl, who is a key character in the story. The Hero Girl is voiced by a different actress, contributing to the diverse cast of characters in the film.
