Looks like homework/exercise given to you. Did you try to write queries by yourself? :)
You may ask your doubts/confusion.
-- 1)
SELECT e.empid
,e.empname
FROM employee e
LEFT JOIN dept d ON e.empid = d.empid
WHERE d.empid IS NULL
--2)
SELECT MAX(d.salary)
,d.deptid
,e.empName
FROM dept d
FULL JOIN employee e ON d.empid = e.empid
GROUP BY d.deptid, e.empname
