Unity not destroying object

Question

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ArrowScript : MonoBehaviour
{
    void OnCollisionEnter2D(Collision2D collision)
    {
        //GameObject effect = Instantiate(hiteffect, transform.position, Quaternion.identity);
        //Destroy(effect, 5f)

Answer 1

OnTriggerEnter2D worked but I had a bug where it said I was still using it it was because the arrow was inside my player that it was summoning from so the prefab was getting instantly destroyed. Thanks for all the help
