Answer:
For CH3Br, there are a total of 14 valence electrons. Hydrogen always goes on the outside, and since Carbon is less electronegative than Bromine, we'll put the Carbon in the center and the Bromine on top. We have 14 valence electrons for the CH3Br Lewis structure. Put two between atoms to form chemical bonds.
Explanation:
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.
