2D sprite won't destroy on collision

i tried variety of ways but i cant seem to be getting a result , basically i want to destroy a 2d ball when it touches another object void OnTriggerEnter2D(Collider2D coll) { if (coll.gameObject.name == "ball") { Destroy(coll.gameObject); } } on 3d it works fine but in 2d it doesn't work any idea ? (of course in 3d i have to remove the 2D from oncollision and collision2D or Collider2D)
