💡 Solution & Explanation

# Analysis of Stereoisomers in Compound X **Identify the stereocenters:** The compound has a C=C double bond with two different cyclopropyl groups attached. The key is recognizing stereoisomery arising from: 1. **Chiral center at C1** (marked with $*$): Bears $H$, $OH$, $CH_3$, and the $C=C$ group — all different substituents → **1 stereocenter** (R/S configuration possible) 2. **C=C double bond** (marked with $**$): The carbon atoms on either side have different substituents: - Left carbon: $H$ and $CH_3$ groups - Right carbon: Two different cyclopropyl-type groups ($CH_2-CH_3$ vs $CH_3$) This creates **geometric (cis/trans) isomerism** → **2 possibilities** (E/Z configuration) **Count total stereoisomers:** Using the formula: Total stereoisomers = $2^n$ where $n$ = number of independent stereocenters/double bonds $$\text{Total isomers} = 2^1 \text{ (chiral center)} \times 2^1 \text{ (double bond)} = 2 \times 1 = \boxed{2}$$ Alternatively: 1 chiral center (2 enantiomers) with a fixed double bond geometry = **2 stereoisomers** **Answer: (B) 2**
