Interpretation Introduction

Interpretation:

The starting percentage of acetonitrile in acetonitrile/water isocratic elution in reversed-phase separation of reaction has to be given.

Concept Introduction:

Reversed-phase chromatography:

One of the most common mode of HPLC is the reversed-phase chromatography.  In reversed-phase chromatography, the mobile phase is more polar and the stationery phase is nonpolar or weakly polar.  The solute is more rapidly eluted from the column in reversed-phase chromatography as the mobile phase is polar.  Less polar mobile phase (solvent) has a high mobile phase strength.

This method is adequate to separate mixtures of low molecular mass.

To give the starting percentage of acetonitrile in acetonitrile/water isocratic elution in reversed-phase separation of reaction

HAND DRAW
Predict the major products of the following organic reaction: Some important notes: Δ CN ? • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers. ONO reaction. Click and drag to start drawing a structure.
