5A Explain which of the following statements are true and which are false. i. N,N'-dicyclohexylurea (DCU) is the dehydrating reagent that converts a carboxylic acid to the corresponding anhydride. ii. The fact that carbonyl compounds have a lower boiling point than alcohols with the same C atoms is because the molecular dipole moment of carbonyl compounds is less than that of alcohols. iii. 3-Methylbut-2-en-2-ol is the only tautomeric structure of 3- methylbutan-2-one.

(1) Predict the outcome of the addition of HBr to (a) trans-2-pentene, (b) 2-methyl-2-butene, and (c) 4-methylcyclohexene. How many isomers can be formed in each case? (2) Addition of HBr to 3,3-dimethyl-1-butene gives a mixture of two isomeric alkyl bromide products. Draw structures for the two products, and give a mechanistic explanation for their formation.

Help me please

b) Use curved arrows to explain the formation of the product. Comment on whether the reaction will yield a racemic mixture or a single enantiomer. ОН H,SO4 H20

1 mol NH3 + 1 mol C2H5Cl when heated there is a lot of unreactd NH3 (about 80%). Why does this occur? How do nucleophiles and electrophiles play a role in this?

Use a sheet of paper to answer the following question. Take a picture of your answers and attach to this assignment. n-Pentanol (CH3CH2CH₂CH₂CH₂OH) and 2-methylbutan-2-ol (CH3CH₂C(CH3)2OH) are converted to their corresponding alkyl chorides on being reacted with hydrogen chloride. (a) Write out an equation for each reaction (b) Assign each the appropriate symbol (SN1 or SN2) (c) Write a suitable mechanism for each reaction

Draw the structures of all the possible products that can be obtained from the dehydration of 2-methylcyclohexanol. Using curved arrows, write a detailed mechanism to show how each product is formed. Indicate which product would be the major one.

A number of substances containing positively polarized carbon atoms have been labeled as "cancer suspect agents" (i.e., suspected carcinogens or cancer-inducing compounds). It has been suggested that the presence of such carbon atoms is responsible for the carcinogenic properties of these molecules. Assuming that the extent of polarization is proportional to carcinogenic potential, how would you rank the compounds with regard to cancer-causing potency?
