Interpretation Introduction

Interpretation: The geometry of all the atoms (except hydrogens) has to be predicted for the given compound.

Concept Introduction:

According to VSEPR (Valence Shell Electron Pair Repulsion) theory, each molecule gets a unique structure. That structure is explained by considering steric number of that molecule.

The steric number is the combination of both number of σ-bonds and number of lone pairs involved in a particular molecule.

σ-bonds are formed by the mutual sharing of electrons between the two atoms. As a result, bond between two atoms is formed. This type of bond is called covalent bond. In this process, bonding electron pairs are involved.

Non-bonding electrons are not involved in the bond formation. They are called lone pairs.

The geometry of the atom will be determined by counting the steric number followed by the hybridization state of that atom and finally electronic arrangement of atoms in space.

If the steric number is 4, the atom has sp³ hybridization and the electronic arrangement of atoms in space (i.e. geometry) will be tetrahedral.

If the steric number is 3, the atom has sp² hybridization and the electronic arrangement of atoms in space (i.e. geometry) will be trigonal planar.

If the steric number is 2, the atom has sp hybridization and the electronic arrangement of atoms in space (i.e. geometry) will be linear.

To find: The geometry for all the atoms in the given compound

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
