Answer
We just need to find some truth values of $p,q$ and $r$ for which both statement gives different result.
Let us assume $p$ is true, $q$ is false and $r$ is also false. Now the first statement will become $F\rightarrow F$ which is True, but the right statement becomes $F\land T$ which is False, hence both statements give different result.
