Chiral class 12
WebCBSE 2024 Class 12th Exam is approaching and candidates will have to make the best use of the time available towards the last stage of your CBSE Class 12th Chemistry Preparation. To help you with that, below we have provided the Notes of 12 Chemistry for topic Haloalkanes and Haloarenes. Class: 12th Subject: Chemistry WebThe atoms attached to C5 are C, H, H. There is no difference. To decide between C2 and C5, we must go one atom further out. From C2, C3 has F, C, H. From C5, C4 has C, H, H. C2 is therefore #2, and C5 is #3. If you assign these priorities to the groups, the sequence 1 → 2 → 3 goes in a counterclockwise direction (S).
