Interpretation Introduction Interpretation: In the increasing order of their dipole moments, the given molecules are to be arranged. Concept Introduction: Explanation The term dipole moment refers to the quantitative measure of polarity of a bond. It is represented as μ . It can be defined as the product of the charge Q and the distance r between the charges. So, its mathematical representation is μ = Q × r . The dipole moment will be created by the charge separation in a polar molecule. For example: The diatomic molecule HCl possess dipole moment due to the charge separation in it as shown here: The crossed arrow represents the direction of the shift of electrons towards the highly electronegative chlorine atom form the least electronegative hydrogen atom. The given molecules are: Compounds (b) and (d) have symmetric structures. So, all the possible bond moments will be equal in magnitude although they are opposite in directions. Thus in compounds (b) and (d), all the bond moments cancel out each other. As a result the dipole moment will be zero in these two compounds and thereby these compounds become non-polar. The bond moments in compounds (b) and (d):

Formal Charges

Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be ne…

Synthesis of Ibuprofen-Part 2: 1. Some pain relievers including ibuprofen (MotrinⓇ) and naproxen (Aleve®) are "α-arylpropanoic acids." Look up the structure of naproxen (AleveⓇ), another a-arylpropionic acid. Using the same reactions that we used for making ibuprofen, show how to make naproxen from the compound below. Show all intermediates and reagents in your synthesis. Show how you would prepare ibuprofen starting from p-isobutylbenzene rather than p-isobutylacetophenenone. What reaction steps would need to change/add? 3. What signals appeared/disappeared/shifted that indicate that you have your intended product and not starting material? What other impurities are present in your product and how do you know?
