What is the ‘structural formula’ of methane? ethane? brainliest answer

CH₄ is Methane, each line = a bond to complete Carbon's Valence shell and each of Hydrogen's as well!

Part 1.

Structural formula of methane:

The chemical formula of methane is CH4.Its structure contains 4 covalent bonds. Four atoms of hydrogen are making 4 covalent bonds with one carbon atom.One carbon atom has valency of 4 electrons.It gets stable by sharing 4 electrons with four hydrogen atoms having one valence electron each.Part 2.

Structural formula of ethane:

The chemical formula of ethane is C2H6.

Its structure contains 7 covalent bonds. Six atoms of hydrogen are making 6 covalent bonds with two carbon atoms.One carbon atom has valency of 4 electrons.There is one C-C covelent bond.One gets stable by sharing 3 electrons with 3 hydrogen atoms having one valence electron each.So net bonds with H are 6 and With each other is one.

C) electrons encircling a nucleus with neutrons and protons
