Question

1. the shorter the fatty acid chain, the more liquid the fatty acid. true false 10) unsaturated fatty acids have adjoining carbons that are connected by a double bond. true false 11) foods rich in saturated fatty acids tend to be liquid at room temperature and have lower melting points. true false 12) a cis formation occurs when the hydrogen atoms next to the double bonds are on the same side of the carbon chain. true false

Explanation:

1. Shorter - chain fatty acids have lower melting points and are more liquid.
2. Unsaturated fatty acids have at least one double - bond between adjoining carbons.
3. Saturated fatty acids are usually solid at room temperature and have higher melting points.
4. A cis - isomer has hydrogen atoms on the same side of the double - bond in the carbon chain.

Answer:

1. True
2. True
3. False
4. True
