The limiting reactant is salicylic acid (C₇H₆O₃).
Explanation:
We have the following chemical reaction where salicylic acid (C₇H₆O₃) reacts with acetic anhydride (C₄H₆O₃) to form acetylsalicylic acid (C₉H₈O₄) and acetic acid (C₂H₄O₂):
C₇H₆O₃ + C₄H₆O₃ → C₉H₈O₄ + C₂H₄O₂
We have started with 70.0 g of salicylic acid (C₇H₆O₃) and 80.0 g acetic anhydride (C₄H₆O₃).
First we calculate the number of moles of each reactant:
number of moles = mass / molar weight
number of moles of salicylic acid = 70 / 138 = 0.507 moles
number of moles of acetic anhydride = 80 / 102 = 0.784 moles
We see from the chemical reaction that 1 mole of acetic anhydride (C₄H₆O₃) reacts with 1 mole of salicylic acid (C₇H₆O₃) so 0.784 moles of acetic anhydride (C₄H₆O₃) will react with 0.784 mole of salicylic acid (C₇H₆O₃) but we only have 0.507 moles of salicylic acid (C₇H₆O₃). The limiting reactant is salicylic acid (C₇H₆O₃).

The answer is (4) hexyne. The definition of unsaturated hydrocarbon is that there is one or more double bonds between carbon atoms. In hexanal and hexanoic acid, there is also double bond but it is not between carbon atoms. So they are not unsaturated hydrocarbon.
