Which is a general representation of a secondary amine?

Secondary amine contain a single hydrogen atom in its alpha carbon.

Explanation:

Secondary amine is also called 2° amine.Amines are named so because they contain -NH2 as functional group.

  The carbon that is adjacent to the functional group here it is -NH2 is called alpha carbon.

  If the alpha carbon of that amine comound contain a single hydrogen atom,then it is termed  as secondary amine.

  For example isopropyl amine.

RNH2

Explanation:

A primary amine is one in which the nitrogen of the amine functional group is connected to only one carbon atom. Hence there are two nitrogen atoms connected to nitrogen as shown above. This is called the general formula for primary amines and serves the purpose of a general representation for primary amines.

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.
