cis-3-hexene overset("(a)")to meso 3,4-...

cis-3-hexene ` overset("(a)")to` meso 3,4-hexanediol trans-3-hexene `overset("(b)")to` meso 3,4-hexanediol. Choose pair of reagent (a, b) for above conversions.

A

Cold ` KmNO_4 , OsO_4 `

B

cold `KmnO_4 , RCO_3 H // H_(3)O^(O+)`

C

`RCO_3H // H_(3)O^(O+) ` cold `KmnO_4`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
a = Cold `KMnO_4` (syn-addition)
`b = RCO_3H//H_3O^(o+)` (anti-addition)
