How do I make it so a death animation will play when I hit an enemy?

Hi guys, I am working on a 2d infinite runner game, and I don't know how to play a death animation when I hit an enemy. I added a 2D box collider and a 2D rigidbody, but I don't know how to make it so that when the player is running and hits an enemy, a death animation plays? Here is my script:

 using System;
 using UnityEngine;
 using UnityEngine.SceneManagement;
 
 namespace UnityStandardAssets._2D
 {
     public class Restarter : MonoBehaviour
     {
         
         void OnCollisionEnter2D(Collision2D coll)
         {
             if (coll.gameObject.tag == "Enemy")
                 GetComponent<Animation>().Play("RedGianDEATHTOALL"); 
             {
                 
                     if (coll.gameObject.tag == "Enemy")
                         coll.gameObject.SendMessage("ApplyDamage", 10);
             }
         }
     }
 }

Any ideas?

A.K.A, Ignore the title of my script. I just edited a script that came with Unity3D
