A wittig reaction occurs when 4-methylbenzaldehyde and benzyltriphenylphosphonium chloride are stirred together at room temperat
GarryVolchara [31]

Answer:

See explanation

Explanation:

The wittig reaction is an organic reaction in which an aldehyde or a ketone reacts with a phosphonium ylide to give an alkene. This phoshonium ylide that participates in the reaction is usually generated insitu in the system by reaction of an alky or aryl triphenylphosphonium halide salt with a base(sodium hydroxide is mostly used).

In this particular reaction 4-methylbenzaldehyde and benzyltriphenylphosphonium chloride were reacted together in the presence of sodium hydroxide and the product with the structure shown in the answer was obtained as the major isomer produced in the reaction.

water decomposes in an evacuated 2.00L container. If you started with 20.0 grams of water, determine the total resulting pressur
Deffense [45]

Resulting pressure is 13.6 atm.

<u>Explanation:</u>

Using Ideal gas equation, we can find the pressure of the gases formed in the reaction.

PV = nRT

Number of moles, n = given mass / molar mass = 20 g / 18 g/mol

                           = 1.11 moles

Volume, V = 2 L

Temperature, T = 25°C + 273 = 298 K

R = gas constant = 0.08206 L atm K⁻¹ mol⁻¹

P = nRT/V

 = 1.11×0.08206 ×298 / 2

 = 13.6 atm

If two electrons have same number of protons but different number of neutrons can they be atoms of the same element?
Illusion [34]
If two atoms** have the same number of protons, they are the same element. They have the same atomic number. The only thing that would change with the number of neutrons is the mass number.
