Answer:
The Lewis structure is shown below.
Explanation:
In the molecule given, the central atom is the carbon (C), which must do 4 bonds. The other carbons at the molecule must do 4 bonds too, and the hydrogens must do only one bond. So, the central atom does a double bond with each carbon, and each carbon does a single bond with the two hydrogens they're bonded.
After the bonds, the central carbon has no lone pairs of electrons, so the geometry of the molecule must be linear, as shown below.
Answer:
C. A solution that cannot dissolve any more solute.
