Answer 1

Ans_48 거 앰 chz COH CH3 Liso CH3 rotation (180°) only one carbon) CH3 percum B7 convert into I fisher so option ② is correct CH3 I I som -Br on Trucu OH H- we can check our answer tua using R and configuration also Cha so carton I-S carbon I -R ch3 chao ⓇY BV now we check n R&S configuration for our andwer. I v cha fuum Br ②CH3 o n - Carbon-I-s n 2 B6 carbon - II - R therefore hence both struten - have some Rands configuration vur andwer is correct.
