Homework Answers
Option B is correct answer. Wittig reagent
PPh3=CH2 is a wittig reagent it react with aldehyde(propanal) it will give terminal alkene as a product.
Option A- It will give 2Butene as product due to H3PO4 as a reaget.
Option C-Soduim borohydride it will reduce a aldehyde to alcohol and give propanol.
Option D -It will give a Butanal as product not give Butene.
Due to this Option B is
correct option.
