In addition to displacing halide ions, the acetylide ion also adds to carbonyl groups. 2-Methyl-3-butyn-2-ol (MBI) is an acetylenic alcohol used in the manufacture of products for the agrochemical and specialty chemical industry. It can be synthesized by the addition of acetylene to acetone to form the alkoxide ion and, as a second step, protonation of the alkoxide ion to produce the alcohol. Complete the mechanism for 2-methyl-3-butyn-2-ol production by drawing in the products of each step and the missing curved arrows. Sodium amide deprotonates the terminal alkyne to form sodium ethynide. Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the canvas and connecting them with bonds. Add charges where needed. Electron flow arrows should start on an atom or a bond and should end on an atom, bond, or location where a new bond should be create

The Michael reaction is a conjugate addition process wherein a nucleophilic enolate anion (the donor) reacts with an α,β-unsaturated carbonyl compound (the acceptor). The best Michael reactions are those that take place when a particularly stable enolate anion is formed via treatment of the donor with a strong base. Alternatively, milder conditions can be used if an enamine is chosen as the donor, this variant is termed the Stork reaction. In the second step, the donor adds to the β-carbon of the acceptor in a conjugate addition, generating a new enolate. The enolate abstracts a proton from solvent or from a new donor molecule to give the conjugate addition product. Draw curved arrows to show the movement of electrons in this step of the mechanism.

Many drugs are sold as their hydrochloric salts (r2nh2+cl−), formed by reaction of an amine (r2nh) with hcl. part 1 out of 4 draw the major organic product formed from the formation of acebutolol with hcl. acebutolol is a β blocker used to treat high blood pressure. omit any inorganic counterions.


Answer: -

Many drugs are sold as their hydrochloric salts (RNH₃⁺Cl⁻), formed by reaction of an amine (RNH₂) with HCl.

It is done because amines are generally liquids. But their hydrochloric salts are solid. A solid drug is always more preferable for drug companies as their handling and packaging are easier.

Acebutolol consists of one amide functionality as well as a secondary amine functionality.

When HCl is added, the lone pairs of the nitrogen of the secondary amine attacks it, leading to the formation of it's hydrochloric salts.

When you convert feet to inches, how do you decide which portion of the conversion factor should be in the numerator and which in the denominator?


Answer : The conversion used is, 1\text{ feet}=12\text{ inches}

Explanation :

The conversion used :

1\text{ feet}=12\text{ inches}

For example : To convert 10 feet into inches.

1\text{ feet}=12\text{ inches}

10\text{ feet}=10\text{ feet}* \frac{12\text{ inches}}{1\text{ feet}}

                    =120\text{ inches}

From this we conclude that, the conversion factor used in the numerator and denominator for 1 feet should be, \frac{12\text{ inches}}{1\text{ feet}}

Final answer:

When converting from feet to inches, use the conversion factor 12 inches/1 foot. This way, the unit 'foot' cancels out and leaves 'inches', performing the conversion. An example is converting 5 feet to inches is 5 times 12, which equals to 60 inches.


When you're converting units, such as feet to inches, the main guideline is to set up your conversion factor in a way that cancels out the unit you want to convert from and leaves you with the unit you want to convert to. In this case, since you're converting from feet to inches, you'll be using the fact that there are 12 inches in 1 foot as your conversion factor. Therefore, when converting, the conversion factor should be set up as 12 inches/1 foot. This in essence means you're multiplying by the number 1, which doesn't change the value, just the units.

For instance, if you have 5 feet and you want to convert this to inches, you'll set your conversion factor up as 12 inches/1 foot, with inches in the numerator and feet in the denominator, to cancel out feet. Multiply 5 feet by the conversion factor (12 inches/1 foot), the result would be 60 inches. Here, the 'feet' units cancel leaving the answer in inches, completing the conversion.

Question 16 Unsaved Which of the following diagrams represents the correct cycling of gases?A) Photosynthesis O2 Respiration CO2
B) Respiration O2 photosynthesis CO2
C) Photosynthesis H2 Respiration O2
D) Respiration CO2 photosynthesis H2


the answer is A:

Photosynthesis release O2 (oxygen)

then animals use oxygen for respiration and release Co2

Final answer:

The correct answer is A) Photosynthesis O2 Respiration CO2. Photosynthesis converts CO2 to O2, which is then used in respiration to be converted back into CO2. Both processes together create a continuous cycle.


The correct diagram that represents the cycling of gases between photosynthesis and respiration is A) Photosynthesis O2 Respiration CO2. Through the process of photosynthesis, plants convert carbon dioxide (CO2) and sunlight into oxygen (O2) and glucose. Organisms, including the plants themselves, then use that oxygen for respiration, during which they convert the oxygen back into carbon dioxide. The glucose is used for energy. This continuous cycling plays a critical role in life on Earth.

The information below describes a redox reaction.Cr3+(aq)+2Cl-(aq)---->Cr(s)+Cl2(s)
Cr3+(aq)+3e- ---->Cr(s)

What is the final, balanced equation for this reaction?

2.) 2Cr3(aq)+2Cl-(aq)+6e- --->Cl2(g)+2Cr(s)
3.) Cr3+(aq)+6Cl-(aq)+3e- ---->2Cr(g)+3Cl2(g)
4.) Cr3+(aq)+2Cl-(aq)------>Cr(s)+Cl2(g)


Answer: option 1)  2Cr3+(aq)+6Cl-(aq) ------> 2Cr(s)+3Cl2(g)


1) Write the oxidation half-reaction:

2Cl^-(aq)---\ \textgreater \ Cl_2(g)+2e^-

2) Write the reduction half-raction:

Cr^(3+)(aq)+3e^(-)---\ \textgreater \ Cr(s)

3) Multiply each half-reaction by the appropiate coefficient to equal the number of electrons of both half-reactions.

6Cl^(-)(aq)---\ \textgreater \ 3Cl_2(g)+6e^(-) 2Cr^(3+)(aq)+6e^(-)---\ \textgreater \ 2Cr(s)

4) Add both half-reactions

2Cr^(3+)+6Cl^(-)(aq)---\ \textgreater \ 2Cr(s) +3Cl_2(g)

And that is the answer. You can count the atoms and charges on every side and check they are equal.

Then you add aqeuos KOH to get C2H5OH
C2H5Cl+KOH-> C2H5OH+ KCl.
Then you add KMnO4 to get the rquired compound.

What would the initial pH of a acetate/acetic acid buffer system (pKa = 4.75) if the concentration of acetate is 1.36 × 10-2 molar and the concentration of acetic acid is 1.64 × 10-1?A.



B) pH = 3.67


pH = pK_(a) +log([A^(-)])/([HA]) \n

pH = 4.75+log([1.36*10^(-)2])/([1.64*10^(-1)]) = 3.67
