Which step in naming unsaturated hydrocarbons is used for alkenes but not alkynes?
a. identify the longest chain of carbon atoms.
b. examine the multiple bond for cis- and trans- isomers.
c. number the chain of carbons, starting with the end nearest the multiple bond.
d. add a number prefix indicating the first carbon atom in the multiple bond.

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.

if it's not useful, feel free to report for mistake in answer.

wher is the rest of the question
