4-methyl-1 -pentene reacts with hydrogen bromide. a. Draw a structure for the carbocation intermediate that leads to the major Markovnikov product in the reaction of hydrogen bromide with 4-methyl-1-pentene. b. Using Markovnikov's rule, draw a structure of the major organic product formed in the reaction of hydrogen bromide with 4-methyl-1-pentene.

The synthesis of cyclohexanone oxime from cyclohexanone is a net? a. elimination b. substitution C. addition d. rearrangement The synthesis of cyclohexanone oxime from cyclohexanone is a net of carbon? a. reduction b. oxidation C. not a redox of carbon Balancing the equation of all the starting reagents going to final products in the synthesis of cyclohexanone oxime from cyclohexanone (see the first question), what is the coefficient of water if the coefficient of cyclohexanone is one? Give your answer in decimal form with no units. Answer: Select all the effects that you should see in an infrared going from cyclohexanone to cyclohexanone oxime. Selecting wrong answers may give you a negative score. a. a peak should disappear from above 3000 cm -1 b. a new peak should appear above 3000 cm -1 c. the frequency of the infrared absorption should go down in the double bond region d. the frequency of the infrared absorption should go up in the double bond region
