Analyze the cyclic alkene cyclopentene. What is the total number of -hydrogen atoms available to par — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

In cyclopentene, the $C=C$ double bond exists between C1 and C2. The adjacent $sp^3$ hybridized carbons are C3 and C5. Each of these adjacent carbons is a completely saturated $CH_2$ group containing 2 hydrogens. Total $\alpha$ -H = 2 + 2 = 4.
