What makes water a polar molecule?

• It shares electrons equally within its covalent bonds, thus making the molecule neutral overall and not charged.

• Electrons are shared unequally within its covalent bonds, thus creating positively charged and negatively charged areas on each water molecule.

Which of the following molecules are considered to be inorganic? (I could not get the numbers to format as subscripts, so I added spaces so you could see them clearly.)

• CuSO4 H2O

• C6H12O6

• C12H22O12

Which of the four molecular structures would you expect to be a type of lipid, which is nonpolar and unable to dissolve in water?

• A

• C

• D

• B

Which of the four molecular structures would you expect to be a carbohydrate like glucose?

• A
• C
• D

• B
