Ncert Exercises & Solutions

Match the reagent from Column I which on reaction with CH₃-CH=CH₂ gives the same product given in Column II as per the codes given below

Column I		Column II
A.	O₃/Zn+H₂O	1.	Acetic acid and CO₂
B.	KMnO₄/H⁺	2.	Propan-1-ol
C.	dil. KMnO₄/OH^-	3.	Propane-1,2-diol
D.	B₂H₆/NaOH⁺ and H₂O₂	4.	Acetaldehyde and formaldehyde

Codes:

Hint: dil KMnO₄/OH^- is a beayer's reagent

The reaction is as follows:

Column I	Column II
A. O₃/Zn+H₂O
B. KMnO₄/H⁺	${CH}_{3} CH = {CH}_{2} \to_{H^{+}}^{{KMnO}_{4}} \underset{Acetic acid}{{CH}_{3} COOH} + {CO}_{2}$
C. dil. KMnO₄/OH^-
D. B₂H₆/NaOH⁺ and H₂O₂	${CH}_{3} CH = {CH}_{2} \to (ii) NaOH / H_{2} O_{2}$ $(Hydroboration$ $o idationx) (i) B_{2} H_{6} \underset{propan - 1 - ol}{{CH}_{3} {CH}_{2} {CH}_{2} OH}$
