Let us give the truth value pq,p\to\sim q, if qpq\to\sim p is false. Taking into account that the implication srs\to r is false if and only if ss is true and rr is false, we conclude that qq is true and p\sim p is false. It follows that pp is true and q\sim q is false. Therefore, we get that the truth value of pqp\to\sim q is false.
