Question

which fat is most likely a solid at room temperature?
one that is saturated
one that is unsaturated
one with double bonds
one that contains no hydrogen

Explanation:

Saturated fats have straight - chain fatty acids without double bonds. This allows them to pack closely together, increasing intermolecular forces. Unsaturated fats (with double bonds) have kinks in their chains, preventing close packing. Fats must have hydrogen. Saturated fats have higher melting points and are more likely to be solid at room temperature.

Answer:

one that is saturated
