Options
- Aa → iii ,   b → iv ,   c → i ,   d → ii
- Ba → ii ,   b → i ,   c → iv ,   d → iii
- Ca → iii ,   b → i ,   c → iv ,   d → ii
- Da → ii ,   b → iv ,   c → i ,   d → iii
Correct answer
D. a → ii ,   b → iv ,   c → i ,   d → iii
Step-by-step solution
a → ii Sand Meyer reaction b → iv Gatterman reaction c → i Wurtz reaction d → iii Fittig reaction The Wurtz reaction is a very useful reaction in the fields of organic chemistry and organometallic chemistry for the formation of alkanes. In this reaction, two different alkyl halides are coupled to yield a longer alkane chain with the help of sodium and dry ether solution.
