Question

water is a strongly polar molecule. think about the following household substances, which would be a nonpolar molecule?
rubbing alcohol
vegetable oil
corn syrup
white vinegar
question 9 (1 point)
oxidation is the loss of elections from an atom or molecule.
true
false

Explanation:

• For the first question:
• Rubbing alcohol (\(C_3H_8O\)) has polar - OH group.
• Corn syrup contains sugars (like glucose \(C_6H_{12}O_6\)) which have many polar - OH groups.
• White vinegar (\(CH_3COOH\)) has polar - COOH group.
• Vegetable oil is made up of long - chain hydrocarbons (non - polar covalent bonds). Non - polar molecules are generally composed of non - polar covalent bonds and have symmetrical electron distribution. Hydrocarbons are non - polar.
• For the second question:
• Oxidation is defined as the loss of electrons from an atom or molecule. For example, in the reaction \(Mg

ightarrow Mg^{2 +}+2e^-\), magnesium is oxidized as it loses electrons.

Answer:

• First question: vegetable oil
• Second question: True
