Answer:
The final product of the reaction is (<em>2S,3S</em>)-2-ethoxy-3-methylpentane.
Explanation:
The given reaction undergoes mechanism in which the nucleophile attacks the backside and it is substituted by the elimination of bromine.
Due to the backside attack of nucleophile , the inverse in stereo-chemistry is observed.
After the substitution of ethoxy group, the configuration is assigned according to the priority it shows clock wise direction(R) - configuration.
When hydrogen faces the front side , it results shows inverse configuration i.e, S- configuration.
The chemical reaction is as follows.
The frequency of light having a wavelength of 425nm will be 70588 × .
The count of times an event takes place per unit of time is known as its frequency. The word frequency would be most frequently used to describe waves in physics including chemistry, including light, sound, including radio waves. The frequency refers to the number of times during one second that a point on a wave crosses a fixed reference point.
A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places in the consecutive cycles.
Given data:
wavelength = 425nm =
Frequency can be calculated by using the formula;
Frequency = speed of light / wavelength
Frequency = 3 × / 425 ×
= 7,0588 ×
.
Therefore, the frequency of light having a wavelength of 425nm will be 70588 × .
