9. C2H5Br + KOH (aq) → C2H5OH + KCl
KCl + AgNO3 → AgBr + KNO3
Yellow ppt

13. CH3—CH(Cl)—CH3 + aqKOH → CH3—CH(OH)—CH3 + NaOI → CHI3
Isopropyl chloride i
CH3CH2CH2C aq KOH → CH3CH2CH2OH + NaOI →Does not give
iodoform test.

19. CH3CH2OH +I2/NaOH →CH3-CHO
3C6H5OH + FeCl3 → (C6H50)3 Fe + 3HC1
C6H5N2Cl → C6H5-N=N-

21. C6H5N2Cl + → C6H5-N=N- (iii) → + Br2
3C6H5OH + FeCl3 → (C6H50)3 Fe + 3HC1
C6H5N2Cl → C6H5-N=N-
(iii) →
+ Br2

22. 1-Propanol (primary alcohol)does not produce turbidity at room temperature with Lucas reagent.
CH3CH2CH2OH anhyd ZnCl2 + HCl → No turbidity at room
2-Methyl-2-propanol(tertiary alcohol) reacts with Lucas reagent (anhyd ZnCl2 + HCl) giving turbidity immediately.
(CH3)3C-OH + anhyd ZnCl2 + HCl → (CH3)3C-Cl
Turbidity immediately

24. CH3—CH(CH3)—OH + 4I2 + 6NaOH → CHI3 + CH3COONa + 5NaI + 5H20

26. CH3CH(OH)CH2CH3 + I2 + NaOH → CHI3
CH3CH2CH2CH2OH + I2 + NaOH → No yellow ppt.

45. 3C6H5OH + FeCl3 → (C6H50)3 Fe + 3HC1
Violet

51. Primary amine can be tested by carbylamine test

53. Primary amine can be tested by carbylamine test

55. C6H5-NH2 +
+ NaOH →
C6H5-

57. →
C6H5SO2N(CH2-CH3)2
