Answer

$CH_3CH_2CH_2CH_2$, SiC

Work Step by Step

From the list, we see that $CH_3CH_2CH_2CH_2$ contains covalent bonding with only london dispersion force. Thus, it has the lowest melting point. SiC contains a network of covalent bonds. Like substances such as diamond, this corresponds to an extremely high melting point.
