Draw the structure of the product for the reaction of propylmagnesium bromide with cyclohexanone. Assume that the reactions are
Nadya [2.5K]

Answer:

See explanation below

Explanation:

This reaction is known as the Grignard reaction. If's often used to add an alkyl to a molecule, in this case, a ketone. This also helps to reduce the carbonile to an alcohol.

The mechanism is taking place in 3 steps.

The first step involves the attack of the pair of electrons of the oxygen from the cyclohexanone to the MgBr, and the other pair takes the propyl.

The second step involves the breaking of this bond to have the OMgBr and the propyl attached to the carbon of the chain.

The last steps involves an hydration of the molecule, to turn the OMgBr into OH, and that would be the final product.

In this case, the final product will be 1-propyl-cyclohexanol.

The picture below, shows the mechanism and the drawing of the final product.

Using the electronegativity values in the chart below, which bond is the most polar?
lorasvet [3.4K]

Answer:

C-O

Explanation:

you have to check the all four bonds and find out their electronegativity difference. Whichever has the largest difference, is your answer.

  1. N-O = 3.04 - 3.44 = -0.4
  2. Cl-Cl = 3.16 -3.16 = 0
  3. C-O = 3.44 -  2.55 = 0.89
  4. C-H = 2.55 - 2.20= 0.35

Now check the differences, the largest electronegativity differences means the most polar bond
