Answer:
True
Explanation:
Ethers react with HI to form the corresponding alcohols and alkyl iodides.
Similarly, ethyl ether react with excess of HI to form ethanol and ethyl iodide. But in the excess of HI as mentioned in the question, ethanol too undergoes reaction with HI to form ethyl iodide.
<u>Hence, ethyl iodide is the only product when ethyl ether reacts with excess of HI for several hours.</u>
Answer: a)
b)
Explanation: Visible light is a form of electromagnetic wave.
Wavelength is defined as the distance between two successive crests of a wave. It is represented as symbol .
Frequency is defined as the number of complete cycles happening per second. It is represented by the symbol .
Wavelength and Frequency follow inverse relation,
where, c = speed of light =
Wavelength and frequency of a wave is usually expressed in a range.
