The maximum number of possible optical isomers in 1-bromo-2-methyl cyclobutane is
- A 4
- B 2
- C 8
- D 16
Answer & Solution
Correct Answer
(A) 4
Step-by-step Solution
Detailed explanation
Electron present on nitrogen atom II and III takes part in conjugation with carbonyl group. Hence, due to this reason availability of electron present on these nitrogen atom decreases simultaneously nucleophilicity decreases. While electron present on nitrogen atom (I) do not take part in conjugation and are most nucleophilic in nature.
