Ethyl bromide is converted to succinic acid by using the following reagents in steps:
A. \(KCN\)
B. \(Br_2\)
C. \(KOH\ (alc.)\)
D. \(H_2O/H^+\)
Choose the correct sequence of conversion:
- A C, B, A and D
- B B, A, C and D
- C D, A, C and B
- D B, C, D and A
Answer & Solution
Correct Answer
(A) C, B, A and D
Step-by-step Solution
Detailed explanation
\(CH_3CH_2Br \xrightarrow{KOH(alc.)} CH_2=CH_2\) \(CH_2=CH_2 \xrightarrow{Br_2} BrCH_2CH_2Br\) \(BrCH_2CH_2Br \xrightarrow{KCN} NCCH_2CH_2CN\) \(NCCH_2CH_2CN \xrightarrow{H_2O/H^+} HOOCCH_2CH_2COOH\) Correct sequence: C, B, A and D
