Homework Answers
As we know that ,
Non -polar solvents are liophillic as they dissolve in non polar substances such as oils,fats,greases.
Now,. For the extraction of persistant organic pollutants/non polar polychlorinated chemicals from edibles such as seaweed, we used the non polar solvents are: Methanol,n-hexane,ethyl acetate,chloroform,benzene,etc.
For red and Brown seaweed extraction we have to use five different solvents namely ,petrolium ether,dichloromethane,chloroform,ethanol,and water.

Objective To extract essential oils and other natural products from the leaves of mentha spicata L. . Reactions Not applicable Procedure 1. Weigh 1.0 g of leaves and place them in a glass mortar. Grind the material until a more or less homogenous mass is obtained. Transfer the ground material into a 100 mL beaker, add a stir bar and 10 mL of water and 10 mL of diethyl ether. Cover the beaker with a watch glass and stir vigorously for 10 minutes...

magnesium sulfate in this lab instead of them?
Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile...

2.) When we take 1H or 13C spectra, we typically use CDCI3 as a solvent. What are the 'H and 13C chemical shifts for this compound? Why does it appear as a triplet in 13C spectra? (Hint: The nucleus of D has a spin of 1.) 3.) How many 13C NMR resonances do you expect for m-xylene and p-xylene, respectively? 4.) Look up the structure of isophorone. How many 'H NMR peaks (ignore splitting) do you expect for this compound?...

than other labs. These are toxicity, volatility, and flammability. We routinely use toxic organic solvents like methanol and acetone that are volatile (have low boiling points), but even solid organic materials can produce vapors that may be toxic. Furthermore, organic materials are flammable, and solvent vapors in the air can and do produce explosive mixtures. You should take some general precautions when doing organic chemistry: Do not get solutions on your skin. You do not need to always wear gloves...

Which one of the following statements is NOT true? We can use the index numbers to determine the percentage change any year from the base year. The weighting percentage for the Paasche Index is always the percentage for the time period for which the index is being computed. The idea is that the prices in the base period should be weighted relative to their current use, not to what that use level was in other periods. You can use the...

Grignard Addition VCL 10-1: Grignard Addition - 1 For this assignment, the target compound that you should synthesize is 1-phenyl-1-propanol. This is an organometallic addition reaction. Examine the product and identify potential bonds that may be formed. Keep in mind the mechanism and the need to quench the reaction with acid to liberate the neutral product. Synthesis Procedures 1.
