Answer:
Dienes are alkenes that contain two carbon-carbon double bonds, so they have the same properties as these hydrocarbons.
In the attached file are the two reactions of dienes production.
Explanation:
Two ways to obtain dienes are as follows:
-Reaction of oxidative dehydrogenation of an alkane, is an exothermic process and occurs at lower temperatures, diene and water are formed, generating greater conversion at lower temperature levels.
-Dehydration of primary alcohols. The treatment of alcohols with acid at elevated temperatures produces dienes due to water loss. For example, heating ethanol in the presence of sulfuric acid produces ethene by the loss of a water molecule.
Answer
6.9 x 10¹²Hz
Explanation:
Given parameters:
Wavelength of the wave = 4.35 x 10⁻⁵m
Unknown:
Frequency of the wave = ?
Solution:
The speed of a wave is related to the wavelength and frequency using the expression below;
C = Fλ
C is the speed of light = 3 x 10⁸m/s
F is the frequency
λ is the wavelength
Insert the given parameters and solve;
3 x 10⁸ = F x 4.35 x 10⁻⁵
F = 
= 6.9 x 10¹²Hz
