(a)

Interpretation Introduction

Interpretation:

Fallowing the each compound structural formula and dipole moments has to be determined.

Concept introduction:

The 1H NMR spectrum of a compound provides some vital information that is required to predict the structure of the compound.  The chemical shift values can predict the groups that are present in the molecule.  The splitting of signals by the (N+1) rule predicts the number of hydrogens or protons attached to the adjacent carbon in a carbon chain of a compound.  With this information, the structure of the compound can be predicted.

Tetra methyl silane: The NMR spectrum of any compound is taken with reference to a standard compound called reference compound.  Generally, tetramethylsilane (TMS) is taken as the reference compound.  The methyl protons of TMS are equivalent and produces only one sharp peak at the rightmost end of the scale.

Dipole moment is defined as a measurement of the separation of two opposite electrical charges. Dipole moments are a vector quantity.

Acridine is a heterocyclic aromatic compound obtained from coal tar that is used in the synthesis of dyes. The molecular formula of acridine is C13H9N, and its ring system is analogous to that of anthracene except that one CH group has been replaced by N. The two most stable resonance structures of acridine are equivalent to each other, and both contain a pyridine-like structural unit. Write a structural formula for acridine.
Phenol (hydroxybenzene) behaves as a weak acid. a) Write out the equilibrium equation for its partial dissociation in water. b) Write out the expression for the acid dissociation constant, Ka. d) Draw the conjugate base of phenol and show how it is stabilised by resonance. e) Compare and explain the acidity of phenol (p = 9.9) with that of: cyclohexanol (pk = 16.0) 3-fluorophenol (pK₁ = 9.3) 4-acetylphenol (pK, = 8.1)
Give reasons for the following :(i) Phenol is more acidic than methanol.(ii) The C—O—H bond angle in alcohols is slightly less than the tetrahedral angle (190°28′).(iii) (CH3)3C—O—CH3 on reaction with HI gives (CH3)3C—I and CH3—OH as the main products and not (CH3)3C—OH and CH3—I.
