A mixture of hex-1-yne, hex-2-yne, and hex-3-yne was hydrogenated in the presence of a nickel catalyst until hydrogen uptake ceased. Assuming that the hydrogenation went to completion, how many different six-carbon hydrocarbons were produced

There will be four different six carbon hydrocarbons

Explanation:

If we look at the compounds carefully, we will discover that the compounds hex-1-yne and hex-2-yne do not exhibit geometric isomerism. This implies that the two compounds will yield only one six carbon hydrocarbon each if the hydrogenation goes to completion.

However, the hex-3-yne exhibits geometric isomerism and exists as the cis-trans isomers. Each of these isomers of hex-3-yne yields six carbons hydrocarbons upon complete hydrogenation. This brings the total number of six carbon hydrocarbons obtained from the mixture to four.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
