What is the value of n in ch3(ch2)nch3 if the make of the hydrocarbon is heptane?

n = 5

Explanation:

methane => 1 Carbon => CH₃

ethane => 2 Carbons => C₂H₆

propane => 3 Carbons => C₃H₈

butane => 4 Carbons  => C₄H₁₀

pentane => 5 Carbons => C₅H₁₂

hexane => 6 Carbons => C₆H₁₄

heptane => 7 Carbons => C₇H₁₆ => CH₃(CH₂)₅CH₃

Octante => 8 Carbons => C₈H₁₈

Nonane => 9 Carbons => C₉H₂₀

Decane => 10 Carbons => C₁₀H₂₂

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.
