Q.10. To 0.5 mL of an unknown alcohol, 5 mL of distilled water and 1 mL of 6M NaOH was mixed in a flask. Iodide reagent solution was then added drop wise up to a total of 25 drops. After about 15 minutes, a bright yellow solid was produced in the flask. The unknown alcohol is options: A) Primary alcohol B) Secondary alcohol having 3 hydrogens on α carbon C) Tertiary alcohol D) Secondary alcohol having no hydrogen on α carbon

A 70% aqueous solution of ethanol in water is commonly used in a laboratory as an antimicrobial solution. The antibacterial gel contains 80% ethanol. It is common to have access to 96% ethanol, answer the following: a.- Is 100% ethanol available? b.- How is it obtained? c.- Does the use of denatured absolute alcohol represent any danger?
Please mark the correct statement below. A. Since 2.1 g of an alkene containing a double bond reacts (exactly) adduction with 8 g of bromine, the closed formula of this alkene is C3H6. B. CH3-CH = CH2 compound has 2 geometric isomers. C. The number of all isomers with the closed formula C4H6 is 7. D. At the same temperature, the vapor pressure of n-propyl alcohol is higher than the vapor pressure of iso-propyl alcohol. E. The reading of the compound CH2 = CHBr - CH2 - CH2 = CH2 is 4-bromo-1,4-pentadiene.
Given are the pairs of alcohols than can be differentiate using Lucas Test EXCEPT? i. (isopropanol and methanol) ii.(ethanol and n-propanol) iii. (t-butyl alcohol and 2-methylbenzyl alcohol) iv.(tert-butyl alcohol and ethanol)
An aldehyde has a boiling point] that is intermediate between an alkane (of the same mass) and an alcohol (also of the same mass). Why is this? Group of answer choices The aldehyde's mass is intermediate between the alcohol and the alkane. The aldehyde molecules interact with each other through dipole/dipole interactions, which are stronger than the interactions between alkane molecules and weaker than the interactions between alcohol molecules. there is no known explanation for the intermediate boiling points of aldehydes. None of the above.
Using a secondary alcohol of your choice as an example: i)give the displayed formula of the product it could be oxidised to ii)state which homologous series the product belongs to iii)write a balanced chemical equation tor the reaction (the convention [O] may be used for the oxidising agent).
in the structure, replace the "A" labels with groups to satisfy all of these conditions:- Put a Br anti to the methyl group already drawn in.- Put a hydroxyl group (OH) gauche to F and anti to Cl.- Put a benzene ring anti to F. (You will need to replace the "A" with a carbon when you do this.)
Unknown Results - Solubility Test: - Slightly soluble Ceric Ammounium Nitrate Test: - Positive Iron (III) Chloride Test: - Negative Chromic Acid Test: - Positive Iodoform Test: - Negative Luca's Test: - Negative The known alcohols tested in this experiment are: Ethanol 1-Propanol 2-Propanol 1-Butanol 2-Pentanol 2-Methyl-2-propanol 1-Octanol Phenol Although you didn't carry out every test on all eight alcohols, you should be able to predict the results for the tests on the alcohols that you did not test. If your unknown alcohol is one of these eight known alcohols, which do you think yours is? Can you definitely identify it? Explain your answer using your test results and predicted results.
Propose a reason(s) for tertiary alcohols being unreactive with most oxidizing agents.
