Part B- The geometric shape is trigonal planar and hybridization is sp2. Part C- The geometric shape is tetrahedral and hybridization is sp3.
A Lewis Structure is a completely simplified illustration of the valence shell electrons in a molecule. It is used to expose how the electrons are organized round character atoms in a molecule. Electrons are proven as "dots" or for bonding electrons as a line among the 2 atoms.
The Lewis structure of urea is attached in the image given below.
The carbon atom surrounded by three regions of electron density. Therefore, it is trigonal planar.
The electron pair geometry is sp2 hybridization.
The nitrogen atoms are surrounded by four regions of electron density. Thus, it is arranged in a tetrahedral geometry. and the hybridization is sp3.
