What function docs the peroxide serve in this reaction? nucleophile electrophile radioal chain initiator acid catalyst Insolvent Circle the most acidic alcohol, cyclohexanol ethanol 2-chlorocthunol isopropanol Which of the following terms best describes reactive nature of a Grignard reagent? electrophile carbocation nucleophile free radical When an ketone is treated with LiAH_4 followed by the addition of water, what is the product? Which of the follow ing solvents would be not suitable for forming a Grignard reagent? What type of orbital do the lone pair electrons on oxygen occupy in ethanol? Which statement does Not apply for the definition for oxidation in organic chemistry: Which is True about the functional group, alcohols? They can form hydrogen bonds They tend to have higher boiling points than ethers. They can be deprotonated using Na metal. All of these Which is the correct name for 6,6-dimethylhept-2-yne 6,6-dimethylhept-3-yne 6,6-dimethylhept-3-yne Which molecule has the highest oxidation state?

Explanation / Answer

I will answer some of your questions, cause I have doubts in some of them. I'll answer the questions that I'm sure they're right.

Question 1.

Usually a pi bond of an alkine is shorter than the pi bond of an alkene, but the triple bond is way stronger than the double bond. So correct option is a).

Question 2:

The structure is as follow: CH3CH2C(CH3)(OH)CH2CH3. The OH is the particular functional group of an alcohol, and it's in a carbon that does not have a hydrogen atom in it's bond. So it's a tertiary alcohol.

Question 3.
The addition of HBr to alkenes in peroxides, just help the sustitutio in the least substituted carbon (anti Zaitsev addition), this happens because ROOR serves as solvent.

Question 4:
By inductive effect, the 2-chloroethanol is the most acidic alcohol, cause the Chloro attracts the electronic density by inductive effect.

Question 5.
The grignard reagent (R-MgBr) just adds to a carbonyl group, and it's an electrophile. It just add to the carbon both molecules (The R to the carbon, and MgBr serves as electrophile).

Question 6.
This reaction is a reduction of the carbonyl group from a ketone to alcohol. Now, if it were an aldehyde, it would be a 1st alcohol, but it's a ketone, so the result would be a 2nd alcohol.

Question 9:
None of the options apply. Usually an oxidation gives as products CO2 and H2O, and this is taking place in the presence of O2, no H2 added or lose.

Question 10.
Alcohols can form hydrogen bonds, so this is the correct option.

Question 11:
Starting the numbering from the right, the triple bond begins in carbon 3, with two methyls in carbon 6, so the correct name would be: 6,6-dimethyl-hept-3-yne.

Hope this helps
