(a)
Interpretation:
An explanation as to why the barrier to the internal rotation about
Concept introduction:
Intermolecular forces are considered as the forces that exist between the atomic moiety carrying dissimilar charges or partial difference in the charges as in the case of dipoles (atoms carrying partial positive and negative charges) and in those which contain hydrogen bonding.
The term, intramolecular hydrogen bonding is used when the hydrogen bonding occurs between two or more molecules.
(b)
Interpretation:
An explanation as to why cis-and trans
Concept introduction:
Isomers are the compounds sharing same molecular formula but differ in the arrangements of atoms and molecules. The stereoisomer is two or more compounds that differ in the spatial arrangement of the atoms. The cis-and trans-isomersim is also known as geometrical isomerism.
(c)
Interpretation:
An explanation as to why
Concept introduction:
The nucleophilic substitution reactions are the reactions in which one nucleophile is substituted by another nucleophile. These reactions depend upon the nucleophilicity and concentration of the nucleophile. The
(d)
Interpretation:
An explanation as to why given compound exist as the enamine isomer rather than an imine is to be stated.
Concept introduction:
Isomers are the compounds sharing same molecular formula but differ in the arrangements of atoms and molecules. The stereoisomer is two or more compounds that differ in the spatial arrangement of the atoms. The resonance proceeds through delocalization of π-electrons present in the aromatic ring and they provide stability to the structure.

Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
