निम्नलिखित यौगिक के मोनोक्लोरीनीकरण से (त्रिविम समावयवियों सहित) कितने उत्पाद अपेक्षित हैं? \( \text{H}_3\text{C}-\text{CH}(\text{CH}_3)-\text{CH}_2-\text{CH}_3 \)

For 2-methylbutane, monochlorination gives 4 structural isomers: 1-chloro-2-methylbutane (1 chiral center = 2 stereoisomers), 2-chloro-2-methylbutane (0 chiral centers = 1 isomer), 2-chloro-3-methylbutane (1 chiral center = 2 stereoisomers), and 1-chloro-3-methylbutane (0 chiral centers = 1 isomer). Total stereoisomers = 2 + 1 + 2 + 1 = 6.
