Why are oils liquid at room temperature?
Due to the existence of carbon to carbon double bonds, the fatty acid chain is kinked and molecules don't pack so tightly together and LDF's are stronger.
Due to the existence of carbon to carbon double bonds, the fatty acid chain is kinked and molecules pack so tightly together and LDF's are weaker.
Due to the existence of carbon to carbon double bonds, the fatty acid chain is kinked and molecules don't pack so tightly together and LDF's are weaker.
Due to the existence of carbon to carbon double bonds, the fatty acid chain is straight and molecules pack so tightly together and LDF's are stronger.
