Q
Q: Which of the following compounds is an alkyne?
Solution: C5H8 is an alkyne, as it follows the general formula C_nH_(2n-2).
Steps: 6
Step 1: Understand what an alkyne is. Alkynes are hydrocarbons that contain at least one triple bond between carbon atoms.
Step 2: Know the general formula for alkynes, which is C_nH_(2n-2). This means for every 'n' carbon atoms, there are '2n-2' hydrogen atoms.
Step 3: Identify the number of carbon atoms in the compound C5H8. Here, 'C5' means there are 5 carbon atoms.
Step 4: Calculate the number of hydrogen atoms using the alkyne formula. For 5 carbon atoms (n=5), the formula gives us: 2(5) - 2 = 10 - 2 = 8 hydrogen atoms.
Step 5: Compare the calculated hydrogen atoms (8) with the given compound (C5H8). They match, confirming that C5H8 follows the alkyne formula.
Step 6: Conclude that C5H8 is indeed an alkyne because it fits the general formula.
