Ah, group ka order toh always I remember as "Please Send Cats, Animals, Monkeys, Zebras" for the common six—easy na? But in our college lab, I keep the reagents lined up from dilute HCl to ammonium sulphide, so students just follow the bottles left to right. Honestly, eigi experience says start with the chart, but your nose will tell you—after years, I can smell a sulphide group from the shelf!
