desrtoying on collision

im simply trying to have my main game obj( a ship) explode and be destroyed when hit by an enemy bullet, but i apparently cant use the word destroy to do this. i was also trying to get the position of the heroship to reset when your hit

function OnCollisionEnter(col : Collision) {
//if(col.gameObject.tag == “enemybullet”)
//return;
//Explode(col.gameObject.transform.position);
//ResetPosition();
if(col.gameObject.tag == “enemybullet”) {
destroy(gameObject== “heroShip”);
}
}

It is called “Destroy”(with a capital D).
