He partial lewis structure that follows is for a hydrocarbon molecule. in the full lewis structure, each carbon atom satisfies the octet rule, and there are no unshared electron pairs in the molecule. the carbon-carbon bonds are labeled 1, 2, and 3. part a how many hydrogen atoms are in the molecule?

4 hydrogen atoms are attached with the carbon atom in the molecule.

Explanation:

Hydrocarbon molecule is a type of molecule which is composed of hydrogen and carbon atoms. Carbon atom belongs to group 4 in the periodic table which means it has four electrons in its outermost shell or orbit, so for attaining octet rule, carbon atom makes 4 covalent bonds with 4 hydrogen atoms and 4 electrons of hydrogen atom is used by the carbon atom and becomes a stable molecule.
