To determine the number of different isomeric alkynes that can give 2,3,4-trimethylheptane on catalytic hydrogenation, we need to analyze the molecular structure of 2,3,4-trimethylheptane and consider the possible isomers.
Step 1: Analyze the molecular structure of 2,3,4-trimethylheptane
2,3,4-trimethylheptane has the molecular formula C10H22. It consists of a straight chain of seven carbon atoms with three methyl (CH3) groups attached to the 2nd, 3rd, and 4th carbon atoms.
Step 2: Identify the possible isomeric alkynes
An alkyne is a hydrocarbon compound that contains a carbon-carbon triple bond. To form 2,3,4-trimethylheptane through catalytic hydrogenation, the alkyne must have a triple bond that is reduced to a single bond.
Step 3: Consider the possible positions of the triple bond
In a straight chain of seven carbon atoms, there are several possible positions for the triple bond. The triple bond can be located between any two adjacent carbon atoms in the chain.
Step 4: Determine the number of isomers
To calculate the number of isomers, we need to consider the possible combinations of triple bond positions.
In a straight chain of seven carbon atoms, there are six possible pairs of adjacent carbon atoms (1-2, 2-3, 3-4, 4-5, 5-6, 6-7). For each pair, the triple bond can be located between the two carbon atoms or absent.
Using the combination formula, the number of isomers can be calculated as follows:
Number of isomers = 2^n
where n is the number of pairs of adjacent carbon atoms.
In this case, n = 6, so the number of isomers = 2^6 = 64.
However, we need to consider the condition that the alkynes should give 2,3,4-trimethylheptane on catalytic hydrogenation. This means that the alkynes should have three methyl groups attached to the 2nd, 3rd, and 4th carbon atoms.
Step 5: Eliminate the isomers that do not meet the condition
Out of the 64 possible isomers, only 8 isomers will have three methyl groups attached to the 2nd, 3rd, and 4th carbon atoms.
Therefore, the correct answer is 8.

Therefore, the correct answer is 8.
