Zinc reacts with hydrochloric acid to liberate Hydrogen gas as it is more reactive than Hydrogen and hence, displace it. Copper is less reactive when compared to Hydrogen and hence cannot displace it

Zinc liberates hydrogen gas when reacted with dilute hydrochloric acid whereas copper does not because it depends on the reactivity of metal to get the hydrogen gas as the product with dilute acid. ... Therefore, copper cannot replace hydrogen from "hydrochloric acid" to form "copper chloride" and hydrogen like zinc.
