(Question)
Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature. Having read the above passage, choose the right answer to the following question (choices are alkane with fewer carbon atoms or alkane with more carbon atoms? ): Kathy did some experiments on two different alkanes and one of the alkanes had twice as many carbon atoms than the other. She would notice that which alkane would require a higher temperature to melt alkane with fewer carbon atoms or alkane with more carbon atoms??
(Answer)
alkane with more carbon atoms?
