A. C5H14
B. C5H12
C. C6H14
D. C6H12

C. C₆H₁₄

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

To find the molecular formula of the model, you simply count and add up the same elements together.

We see that we have 6 carbons and 14 hydrogens. Therefore our answer is C. C₆H₁₄

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.
