(a)
Interpretation:
The shape around the C-1 and the hybridization of C-1 in ethyl iodide has to be predicted.
Concept Introduction:
Molecular geometry: The term molecular geometry refers to the 3-dimensional shape of the molecule by which the molecule is occupying in space with all its surrounding atoms or ions and/or lone pair of electrons.
Hybridization is the phenomenon of intermixing of the atomic orbitals of different energy that results in the formation of a new set of hybrid orbitals which have equivalent energies. The various types of atomic orbitals are: s, p, and d orbitals. Types of hybridization that involves s, p and d orbitals are
(b)
Interpretation:
The shape around the C-1 and the hybridization of C-1 in transition state has to be predicted.

(c)
Interpretation:
While the reaction is run with one of the isomers, the ethyl iodide is not optically active; the reason has to be explained.
Concept Introduction:
Optical isomerism of substituted
Optical isomers are non-superimposable mirror images. The carbon atom attached with four different substituents or group of atoms is known as chiral centre/ asymmetric carbon.

- Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR.
