My today's practical questions 1. How many valancies Mn atom shows and why ? 2. Why transition metals are hard ? 3. Why transition metals show colour ? 4. Which metal in 1st transition series does not show colour? Name its one compound . 5. What is color of CuSO4 in hydrate form and in anhydrous form. 6. Order of stability of carbocation. 7. What is Lucas reagent ? Order of formation of turbidity with Lucas Test. 8. Draw structures of ethanamine and N-methylethanamine. Give test to differentiate among both. I was able to answer all questions. Hoping for best !!

[@Griffin323]

Answers??

[@anamayshukla2645]

U should have googled. Still I am writing hints or concepts here 1. From 2 to 7. Because of half filled d orbital of Mn 2. Due to strong metallic bonding. 3. D-d transition 4. Zn. ZnCl2 is the compound which is white in colour 5. Hydrate: Blue Anhydrous: White 6. 3°>2°>1° 7. ZnCl2 + HCl is Lucas reagent. Turbidity order : 3>2>1 (alcohols) 8. They are 1° and 2° amines respectively. They can be differentiated by Carbylamine test in which only 1° amine will give ethylisocyanide (C2H5NC) which is foul smelling substance. Bless You
