D) a lower; weaker
E) the same; similar

Question

Quizplus · Accepted Answer

A branched alkane has a lower boiling point relative to the isomeric linear alkane because the branches disrupt the close packing of molecules and decrease the surface area available for intermolecular interactions, such as London forces. However, there are still strong London force interactions in the branched alkane because its polarizability is similar to that of the linear alkane.
