A student left some alkyl halides (RC1 and RBr) in an open container for several minutes. What happened to the composition of the halide mixture during that time? Assume that some liquid remains in the container.

Need help ASAP!! thanks! The minimum volume of boiling water is used to dissolve 1.50 g acetanilide.  The hot solution is cooled to room temperature and the acetanilide recrystallizes.  What mass of acetanilide remains dissolved in water? (solubility of acetanile at 100o C is 5 g/100 mL and at room temperature is 0.54 g/100 mL). (Enter a number only with no g unit.)

What reaction will occur when benzoic acid is mixed with sodium bicarbonate? (Hint: benzoic acid is an acid and sodium bicarbonate is a base...) What three products will be generated by this reaction? (You may have to look this one up...) HO. Na HO.

Please explain for both of these reactions why we get the correct numbers in front of the reacted alcohol and h2. how do we determine these numbers   for example in the first reaction from 2 to 2 in the products and no number in front of h2 and then in the second reaction 6 and 2 to 2 and 3h2

Use the following atomic weights and quantities to calculate the overall % yield of 4-chlorocarbonyl-4'-pentyllbiphenyl. Remember that your yield must be based on the stoichiometry (balance the reaction!), the limiting reagent, and that grams must be converted to moles. Filling out most of the chart will help. Give only two significant digits in your answer. If after rounding the answer is a whole number, do not include a decimal point. C = 12, H = 1, CI = 35.5, N = 14, O = 16, S = 32 formula formula weight milliliters density 4-carboxy-4'-pentylbiphenylthionyl chloride dimethylformamide → 4-chlorocarbonyl-4'-pentylbiphenyl 3.678 1.64 6.860 0.944 grams moles 13.314 7.117 Answer: % yield ?

1. Explain why it is important to keep water out of this reaction. What would happen if water got into the reaction mixture? (Note: A small amount of KOH was also added to this reaction). 2. You may have noticed that the reaction was perform at a temperature (85 degrees celsius in a 35 mL microwave reaction vessel) that was higher than the boiling point of methanol (64.7 degrees celsius), how is this possible?

Please help me answer this question. Thank you!

You are asked by your chemistry teacher to find: a) the solubility of different carboxylic acids in water and b) whether there is a connection between solubility and structure of different carboxylic acids. Follow the questions below to design and conduct an experiment to determine an answer to this question. a. From the paragraph above, write a question out that you will try and answer from conducting an experiment (C:2) b. Based upon your knowledge of the physical properties of organic compounds, hypothesize an order of solubility from lowest to highest: (1:3) Organic Compound Order of solubility (1=lowest, 3=highest) Pentanoic acid Hexanoic acid Ethanoic acid c. Provide an overall explanation for your hypothesis based upon your knowledge of physical properties. (A:3) d. Based upon the materials listed below, design a step by step experiment to test your hypothesis. Provide your individual steps. Include all the materials listed below. (1:3) Materials: CH,(CH,4COOH (), CH,COOH (),…

Past paper question

Sn1 reaction in five sentences or less discuss how your product mixture is separated from all reactant and byproducts starting with the desired products and four other components present in the mixture. Begin by indicating how the first component is separated from the others and how the solubility of one compound versus the others in the solvent played a major role in this separation.

2. Look up and draw the structure of each of the following solvents: water, acetone, ethanol, acetonitrile, hexane, dichloromethane, and ethyl acetate. Classify each as non-polar, polar protic, or polar aprotic solvents.

What will happen to Dichloromethane when it is added to Silver nitrate? Does it gives a postive solution? Give an inference why

If exactly 3 moles of propanol (C3H8O) is combusted in the presence of excess oxygen (O2) for form carbon dioxide (CO2) and water (H2O), how many moles of water will be produced? Enter the integer number of moles of H2O, do not enter the unit. Hint: Since this problem and two problems below rely on this reaction, make sure you balance this reaction very carefully on paper as your first step before doing any calculations. The reaction to be balanced is reaction between C3H8O(l) and O2(g) to produce CO2(g) and H2O(l).
