a: alkane ~
b: wet spaghetti
What:
"However, straight chained alkanes have lower m.p. than branched alkanes. Branching increases m.p. as branched molecules can fit more closely together and more energy is needed to separate them; the lattice of a solid straight chained alkane is like wet spaghetti: molecules can easily slide over each other."
