Q

Why don’t we achieve 100% yield?

A

1) If the reaction is reversible then not all the reactants convert to product especially if the reaction is very slow so does not reach equilibrium quickly

2) There may be side reactions that produce by products. This means lower yield of desired product

3) Product may be lost through transferring between vessels and through purification steps e.g filtering
