Interpretation Introduction

Interpretation:

The number of moles of tin ion required to reduce it by one coulomb charge has to be calculated.

Concept introduction:

Electric charge:

Electric charge is defined as magnitude of charge of a mole of electron (1.602×10-19 C)(6.022×1023mol-1)=9.649×1014 C . It is expressed in terms of coulombs (C). 9.649×1014 C is Faraday constant.

The electric charge in coulombs can be expressed as,

q=n.N.F

Where q = coulombs

n = unit charges per molecule

N = moles

F= Coulombsmole e-

Interpreting NMR spectra is a skill that often requires some amount of practice, which, in turn, necessitates access to a collection of NMR spectra. Beyond Labz Organic Synthesis and Organic Qualitative Analysis have spectral libraries containing over 700 1H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish to select other compounds for additional practice. 1. Write the IUPAC names for the following two structures: Question 2 Question 3 2.
