JEE PYQ: General Organic Chemistry Question 18
Question 18 - 2020 (03 Sep Shift 1)
The total number of monohalogenated organic products in the following (including stereoisomers) reaction is _________.
A (simplest optically active alkene) $\xrightarrow{(i)\ \text{H}_2/\text{Ni}/\Delta}$ $\xrightarrow{(ii)\ \text{X}_2/\Delta}$
Show Answer
Answer: (8)
Solution
The simplest optically active alkene undergoes hydrogenation then halogenation. Considering all possible positions and stereoisomers, there are 8 monohalogenated organic products (including 2 pairs of enantiomers and other structural isomers).
