Nucleophilicity is a kinetic property. A higher nucleophilicity indicates that the nucleophile will easily donate its electrons to the electrophile and that the reaction will occur at the faster rate. The reaction rate also depends on the nature of the electrophile and solvent. Rank the following reactions from fastest to slowest based on the nucleophilicity of the nucleophile
From the fastest to the slowest based on the nucleophilicity of the nucleophiles, the order is represented as:
[tex]\mathbf{(CH_3)_2N^- +CH_3 -Br \to (CH_3)_2NCH_3+Br^- \ }\\ \\ \\ \mathbf{CH_3NH^- +CH_3 -Br \to CH_3NHCH_3+Br^- \ } \\ \\ \\ \mathbf{H_3N^- +CH_3 -Br \to CH_3NH_2 + Br^- \ }[/tex]
What are Nucleophilic functional groups?Nucleophilic functional groups include electron-rich atoms capable of donating an electron pair in order to establish a new chemical covalent bond. The most frequent nucleophilic functional groups are:
Water, Alcohols, Phenols, Amines, Thiols, etcThe protonation state of these functional groups has an effect on their nucleophilicity. Also, the trend of nucleophilicity goes from:
Tertiary,Secondary, PrimaryThe following reactions that we are supposed to find their order is given as follows:
[tex]\mathbf{CH_3NH^- +CH_3 -Br \to CH_3NHCH_3+Br^-} \\ \\ \\ \mathbf{(CH_3)_2N^- +CH_3 -Br \to (CH_3)_2NCH_3+Br^-} \\ \\ \\ \mathbf{H_3N^- +CH_3 -Br \to CH_3NH_2 + Br^-}[/tex]
From the fastest trend of the nucleophilicity of the nucleophile to the slowest, the correct arrangement is as follows:
[tex]\mathbf{(CH_3)_2N^- +CH_3 -Br \to (CH_3)_2NCH_3+Br^- \ \ \ ---(2'' \ ^0) \ \\}\\ \\ \\ \mathbf{CH_3NH^- +CH_3 -Br \to CH_3NHCH_3+Br^- \ \ \ \ ---(1^0) } \\ \\ \\ \mathbf{H_3N^- +CH_3 -Br \to CH_3NH_2 + Br^- \ \ \ --- \ \ \ \ (1^0)}[/tex]
The first reaction has two functional groups of methyl (-CH_3) attached to it which increases its nucleophilicity to the second one which has one methyl functional group attached to it.

Which stage is the last stage of speciation? question 5 options: the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring. The populations successfully interbreed. The populations become totally separated from one another. The populations are isolated and thus do not interbreed
Answer:
D) The population become adapted to different environments and eventually becomes so different that they cannot interbreed to produce fertile offspring.
Explanation:
Speciation is divided into three stages:
a) Separation.
b) Adaptation.
c) Reproductive Isolation.
Stage 1: Separation.
A part of the population separates and adapts to a new environment. Natural events such as tsunamis, tidal waves can cause organisms to separate from their initial habitat to a new environment.
Stage 2: Adaptation.
At this stage, the organisms evolve new traits that enable them to a new environment. They possess certain characteristics that enable them to fit into the new environment. Example The great white skin's color makes it difficult for it to be seen in the dark.
Stage 3: Reproductive Isolation.
At this stage, organisms of the same species reunite and do not interbreed. Here, species are isolated into new ones so they have the best adaptations for their new habitat.

Please rate and mark brainliest!!
Note that the probability that Micah is included in the group of students chosen is approximately 0.000305, or about 0.03%.
How to compute the above probabilityMicah's probability of being included in the group of students chosen can be calculated using combinations. There are a total of 28 students in the class, and the teacher is selecting 3 students.
The probability of Micah being chosen can be calculated as:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
Number of favorable outcomes = 1 (Micah being selected)
Total number of possible outcomes = Number of ways to choose 3 students out of 28 = C(28, 3) = 3276
Probability = 1 / 3276
≈ 0.000305
So, the probability that Micah is included in the group of students chosen is approximately 0.000305, or about 0.03%.

Determine the direction of electron flow and label the anode and the cathode. Label each electrode as negative or positive. Drag the appropriate labels to their respective targets
In an electrochemical cell, electrons flow from anode to cathode while current flows in the opposite direction.
What is an electrochemical cell?The question is incomplete but it clearly relates to an electrochemical cell so I will answer in a general way. An electrochemical cell consists of a cathode and an anode. The anode is positively charged while the cathode is negatively charged.
We should note that electrons flow from anode to cathode but the flow of current is in the opposite direction. This occurs because the electron is negatively charged.

You get a $60,000 loan for a new dump truck. With the truck, you can generate $500 more business each week at 80% margin. Your interest rate on the loan is 8. 6%. Does the additional margin generated cover the interest payments?
Assuming your interest rate on the loan is 8. 6%. The additional margin generated will cover the interest payments.
Additional margin
Let determine the weekly interest
Weekly interest= 8.6% /12 x 60,000
Weekly interest= $99.23
Let calculate the amount left since the business generates $500 at a margin of 80
Amount left= 500 x 80%
Amount left= $400
Based on the above calculation we can see that the amount of $400 is sufficient enough to cover the $99.23 payments.

In peas, purple flowers are dominant over white flowers. If two heterozygotes are crossed, what fraction of the population will have white flowers?
The fraction of the population will have white flowers after the crossing of the heterozygotes is; 1/2
What is the result of the heterozygote crossing?P = purple gene
p = white gene
Punnet squares shows the possible genotypes and probabilities of each genotype in the offspring of a cross:
Purple flower genotype (heterozygous) = Pp
White flower genotype = pp
Potential genotypes for offspring are Pp and pp;
According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;
This means 2 should be purple and 2 white which translates to the fact that there is a 50% chance of having either genotype, of being purple or white.
