MCQ
In which case formation of butane nitrile is possible
- ✓${C_3}{H_7}Br + KCN$
- B${C_4}{H_9}Br + KCN$
- C${C_3}{H_7}OH + KCN$
- D${C_4}{H_9}OH + KCN$
✓
Answer
Correct option: A.
${C_3}{H_7}Br + KCN$
a
(a) ${C_3}{H_7}Br + KCN \to {C_3}{H_7}CN + KBr$
(a) ${C_3}{H_7}Br + KCN \to {C_3}{H_7}CN + KBr$
In $ IUPAC$ system the carbon of functional group also take in numbering.
So ${C_3}{H_7}CN$ is butane nitrile.
