The relative energy levels of the three staggered conformations of 2,3-dimethylbutane are needed to be find out. Concept introduction: Conformers arise due to the free rotation of C − C bond. This rotation are measured by dihedral angle , it is the angle between two atoms attached to two different carbons of C − C rotation in Newman projection. The least energy occupied conformer is called staggered conformer , which are having a dihedral angle of ‘60’ degree. Newman projection: Newman projection of molecule is one type of representations for the alkanes , where the projection visualization from one carbon to another carbon. In this Newman projection, front carbon which represented as dot is called proximal and the back carbon which represented as circle is called distal. The atoms attached to the two carbons of C − C renders the energy levels of staggered conformers.

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."
