Explanation:
Step 1: To determine the number of distinct alkynes that can be formed with C6H10, we need to first find the number of possible carbon skeletons for C6H10.
Step 2: The general formula for an alkyne is CnH2n-2, where n is the number of carbon atoms in the alkyne.
Step 3: For C6H10, the number of carbon atoms (n) is 6. Therefore, the general formula becomes C6H2(6)-2 = C6H10.
Step 4: Now, we need to find the number of possible carbon skeletons for C6H10.
Step 5: The number of possible carbon skeletons can be determined by dividing the total number of carbon atoms by 2.
Step 6: For C6H10, the number of carbon atoms is 6. Therefore, the number of possible carbon skeletons is 6/2 = 3.
Step 7: So, there are 3 possible carbon skeletons for C6H10.
Step 8: Now, we need to determine whether each of these carbon skeletons can give effervescence on heating with Na.
Step 9: Alkynes react with Na to form sodium alkynides, which then react with water to produce effervescence (evolution of gas).
Step 10: The carbon skeleton C≡C-C can give effervescence on heating with Na.
Step 11: The carbon skeleton C=C-C≡C can also give effervescence on heating with Na.
Step 12: However, the carbon skeleton C-C≡C-C cannot give effervescence on heating with Na because there are no acidic hydrogens present.
Step 13: Therefore, there are only 2 distinct alkynes for C6H10 that give effervescence on heating with Na.
Step 14: The correct answer is option (b) 2.
