(a)

Interpretation Introduction

Interpretation:

Mixture of three molecules are separated on a C18 column using methanol/water as the mobile phase, following answer is should be identified.

Concept Introduction:

London dispersion force also called an induced dipole-induced dipole attraction is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.

Dipole-dipole interaction results when two dipolar molecules interact with each other through space, there occurs a partially negative charge of one of the polar molecules is attracted to the partially positive charge of the second polar molecule.

Ion-dipole interaction results of an electrostatic interaction between a charged ion and a molecule that has a dipole.

A hydrogen bonding is partially an electrostatic attraction between H atom which is bonded to more electronegative atom such as N, O, orF and another adjacent atom bearing a lone pair of electron.

(b).

Interpretation Introduction

Interpretation:

It should be determine that which molecules is most attracted to the stationary phase, and what are the forces that attract the molecule to the non-polar phase.

Write structural formulas for the major products by doing addition reactions 1. You must add H2 as Pt is catalyst it does not take part in reactions only speed up the process H₂ CH2=CH-CH3 Pt 2. Add HCI break it into H and Cl CH3 HCI 3. Add Br2 only CC14 is catalyst CH3-CH=CH2 B12 CCl4 4. Add water to this and draw major product, H2SO4 is catalyst you have add water H20 in both the reaction below H₂SO4 CH3-CH=CH2 CH3 H2SO4/H₂O CH3-C=CH2 reflux ?
Plan the synthesis of the following compound using the starting material provided and any other reagents needed as long as carbon based reagents have 3 carbons or less. Either the retrosynthesis or the forward synthesis (mechanisms are not required but will be graded if provided) will be accepted if all necessary reagents and intermediates are shown (solvents and temperature requirements are not needed unless specifically involved in the reaction, i.e. DMSO in the Swern oxidation or heat in the KMnO4 oxidation).
