Polyunsaturated

The transcript explains the presence of double bonds in carbon chains, which prevents hydrogen atoms from attaching, affecting the compound's properties. It highlights that polyunsaturated fats, which have multiple double bonds, are typically liquid at room temperature, unlike saturated fats that are solid.

What is a characteristic feature of compounds with two or more double bonds?

• They contain two or more double bonds between carbon atoms.

• They have single bonds only.

• They are always solid at room temperature.

• They do not contain any carbon atoms.

How do double bonds influence the attachment of hydrogen atoms?

• They allow more hydrogen atoms to attach.

• They prevent hydrogen atoms from attaching.

• They have no effect on hydrogen attachment.

• They convert hydrogen atoms into oxygen.

What effect do double bonds have on the properties of a compound?

• They alter the physical and chemical properties.

• They make the compound more acidic.

• They have no effect on the compound.

• They make the compound more solid.

At room temperature, how do polyunsaturated fats typically exist?

• As liquids.

• As gases.

• As solids.

• As crystals.

How do polyunsaturated fats compare to saturated fats at room temperature?

• They are more liquid than saturated fats.

• They are more solid than saturated fats.

• They are the same as saturated fats.

• They are more gaseous than saturated fats.
