The (c6h14)2nh molecule represents a amine.

primary

secondary

tertiary

Secondary .

Explanation:

Primary amine contains only one alkyl group.

Secondary amine contains two alkyl groups.

Tertiary amine contains three alkyl groups.

So, it is secondary amine.

Secondary

Explanation:

Because of this amount of hydrogens being substituted, we can classify the amines in primary (R-NH2), secondary (R1R2NH) and tertiary (R1R2R3N) amines. In the primary amines, only one of the hydrogens is replaced by an organic radical, for example, in the following CH3 - NH2 molecule, in the secondary we have the substitution of two hydrogen atoms, as in the case of CH3 - NH - CH3 and in the tertiary all are replaced.

In the molecule (C6H14) 2NH, the bold part shows the substitution of two hydrogen, so we can classify the molecule as a secondary amine.

the answer is the first option

explanation:

just googled it m8. not that hard

lol

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.
