Question

the molecular structures of linoleic acid and palmitic acid, two naturally occurring substances, are shown in the figure. based on the molecular structures shown in the figure, which molecule is likely to be solid at room temperature? a linoleic acid, because the absence of carbon - carbon double bonds allows the molecules to pack closely together. b linoleic acid, because the presence of carbon - carbon double bonds prevents the molecules from packing closely together. c palmitic acid, because the absence of carbon - carbon double bonds allows the molecules to pack closely together. d palmitic acid, because the presence of carbon - carbon double bonds prevents the molecules from packing closely together.

Explanation:

Saturated fatty - acids (like palmitic acid) without C - C double bonds can pack closely, increasing intermolecular forces and melting point, making them solid at room temp.

Answer:

C. Palmitic acid, because the absence of carbon - carbon double bonds allows the molecules to pack closely together.
