Answer:

The major product formed is a benzyl allyl compound, namely 2-methylene propylbenzene

Explanation:

<u>Part 1.</u>

The product formed from this Wittig reaction with phosphonium ylide is a phenylallyl compound, 2-methylene propylbenzene. Structure and reaction synthesis is attached in file.

<u>Part 2</u>

The types of transformation involved are:

  • alkylation (as there is a transfer of alkyl group)
  • addition (reaction of ylide)

Answer:

2-methylene propylbenzene (major product)

Explanation:

This reaction yields olefins and organophosphorus compound and is also known as wittig olefination. The reactants fits the category of a ketone (1-phenylpropan-1-one) and a Wittig reagent (phosphonium ylide).

Part 1: Answer in the fig. Below.

1-phenylpropan-1-one + phosphonium ylide ➡ phenylallyl compound + 2-methylene propylbenzene (major product)

Part 2.

Classical mechanisms that happened during its transformation are thus;

• nucleophilic addition

• Elimination

• cycloaddition

• [2+2]/retro-[2+2] mechanism.

Proteins have many functions in the cell membrane. Which function is NOT related to a protein?a. transportb. membrane fluidityc.
kirill115 [55]

The function that is NOT related to a protein is:

Membane fluidity.

Membrane fluidity is not related to a protein function because membrane fluidity is a function of lipids not proteins.

Transport and all other options are involved in functions of protein.

MA_775_DIABLO [31]

Answer:

has 4 electrons in its valence shell.

Explanation:

Silicon has 14 protons, so its neutral atom has also 14 electrons, thus, the electron distribution following the Linus Pauling's diagram is:

1s² 2s²2p⁶ 3s²3p²

Thus, it has 4 electrons in its valence shell (3), likely carbon. So, silicon would have some of the properties of carbon, such as form 4 bonds, and the structure would be similar.

What does ''Isotope'' means? &amp;from which language that drives from? answer to me then you will have 20 points help me then y
coldgirl [10]

Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.

The term isotope is formed from the Greek roots isos ("equal") and topos ("place"), meaning "the same place".

Determine the velocity of a 55-kg skier whose kinetic energy is 8900 J
goldfiish [28.3K]

Answer:

Kinetic energy = 1/2mv^2

8900 j =1/2*55*v^2

v^2=8900*2/55

v^2=323.6

v=17.98

How many calories of heat are necessary to raise the temperature of 319.5 g of water from 35.7 °C
rjkz [21]

20600Cal              

Explanation:

Given parameters:

Mass of water = 319.5g

Initial temperature = 35.7°C

Final temperature = 100°C

Unknown:

Calories needed to heat the water = ?

Solution:

The calories is the amount of heat added to the water. This can be determined using;

     H  =   m  c Ф

c  = specific heat capacity of water = 4.186J/g°C

   H is the amount of heat

    Ф is the change in temperature

    H = m c (Ф₂ - Ф₁)

    H = 319.5 x 4.186 x (100 - 35.7) = 85996.56J

Now;

     1kilocalorie = 4184J

     

85996.56J to kCal; \frac{85996.56}{4184}   = 20.6kCal  = 20600Cal
