Consider the Wittig reaction of p‑anisaldehyde with excess chloride in base to make (Z)‑p‑methoxystilbene. chloride (388.9 grams per moles) and p-anisaldehyde (136.2 grams per mole, density equals 1.12 grams per milliliter) react to form p-methoxystilbene (210.1 grams per mole). A reaction was performed in which 0.300 mL of p‑anisaldehyde was reacted with a slight excess of chloride to make 0.449 g of p‑methoxystilbene. Calculate the theoretical yield and percent yield for this reaction.
