Two common methods to generate an aldehyde is by oxidation of an alcohol and through ozonolysis.

kotykmax [81]

Answer:

a. True.

Explanation:

Only primary and secondary alcohols can oxidise to give an aldehyde. But a weak oxidizing agent must be used to prevent formation of a carboxylic acid or ketone.

weak oxidizing agents: Chromyl chloride, silver/oxygen/500°C

take an example of ethanol:

 ${ \bf{CH _{3} CH_{2}OH \: \: \frac{Ag/O_{2} }{500 \degree C} > \: \:CH _{3} CHO}}$ 

 ${ \sf{CH _{3} CHO \: \: is \: ethanal}}$ 

By ozonolysis:

Here, reactants are Ozone gas, Carbon tetrachloride at a temperature (<20°C), ethanoic acid, zinc and water.

take an example of propanol:

if it undergoes ozonolysis, it gives ethanal and methanal.

The formula vw=f⋅λ describes the relationship between the speed of a wave (vw), and its frequency (f) and wavelength (λ). For ex

GrogVix [38]

If the wavelength of the wave is increased to 10 m, the frequency of the wave will be 60 Hz

<h3>Data obtained from the question </h3>

Wavelength (λ) = 10 m
Velocity (v) = 600 m/s

Frequency (f) =?

<h3>How to determine the frequency of the wave </h3>

The frequency, wavelength and velocity of a wave are related according to the following equation:

Frequency (f) = velocity (v) / wavelength (λ)

f = v / λ

With the above formula, we can obtain the frequency of the wave as follow

f = v / λ

f = 600 / 10

f = 60 Hz
