in the 1H NMR spectrum for ethanol, we expect to have peaks (enter number of peaks), with an integration ratio of (enter integration ratio).The farthest downfield peak is for the hydrogen(s) attached to the (enter atom the Hydrogen is attached) in the group (enter chemical formula for the group). The most shielded peak is for the hydrogen(s) attached to the (enter atom the Hydrogen is attached) in the group (enter chemical formula for the group).

a force of 500                  

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.
