Question

part 1
analyze the overall structure of cholesterol. how does the number of nonpolar covalent bonds compare to the number of polar covalent bonds within a single molecule of cholesterol?
cholesterol has about the same number of nonpolar covalent bonds as polar covalent bonds.
cholesterol has more nonpolar covalent bonds than polar covalent bonds.
cholesterol has more polar covalent bonds than nonpolar covalent bonds

part 2
does cholesterol contain many partial charges, or very few partial charges?
many, because it is primarily made of nonpolar bonds.
very few, because it is primarily made of nonpolar bonds.
many, because it is primarily made of polar bonds.
very few, because it is primarily made of polar bonds.

Explanation:

Part 1:

The cholesterol molecule has a large non - polar hydrocarbon structure with only one polar hydroxyl group. Non - polar covalent bonds are between atoms with similar electronegativities (e.g., C - C and C - H bonds), and polar covalent bonds are between atoms with different electronegativities (e.g., O - H bond in the hydroxyl group). There are many more non - polar bonds than the single polar bond.

Part 2:

Partial charges occur due to differences in electronegativity in polar bonds. Since cholesterol is primarily made of non - polar bonds (C - C and C - H), there are very few partial charges.

Answer:

Part 1: Cholesterol has more nonpolar covalent bonds than polar covalent bonds.
Part 2: Very few, because it is primarily made of nonpolar bonds.
