Answer:

Hexane.

Explanation:

Hello!

In this case, since the general reaction of the compound C4H14 with chlorine is:

$C_6H_{14}+Cl_2\rightarrow C_6H_{13}Cl+HCl$

Which stands for a substitution chemical reaction in which one chlorine is able to replace one hydrogen and therefore hydrogen chloride gives off; we infer that the initial compound, C4H14, shows off the $C_nH_{2n+2}$ formula characteristic of alkanes; in such a way, as it has six carbon atoms, we infer it is hexane.

Best regards!
