Wave y and wave z are two types of electromagnetic waves traveling through a vacuum suppose the frequency of wave y is about thr
2 answers:
Answer: The energy of wave-y will more than the energy of wave-z. Since,frequency of wave-z is less than the frequency of wave-y
Explanation:
Let the frequency of the wave z be
Given that frequency of wave y is about three times greater than the frequency of wave-z.
Then frequency of wave-y :
Frequency of wave-z is less than the frequency of wave-y:
The energy of the electromagnetic waves with frequency is given by:
, h= Planck's constant
Energy of the wave is directly proportional to the frequency of the wave.
The energy of wave-y will be more than the energy of wave-z. Since,frequency of wave-z is less than the frequency of wave-y

Answer: (Structure attached).
Explanation:
This type of reaction is an aromatic electrophilic substitution. The overall reaction is the replacement of a proton (H +) with an electrophile (E +) in the aromatic ring.
The aromatic ring in p-fluoroanisole has two sustituents, an <u>halogen</u> and a <u>methoxy group</u>, which are <em>ortho-para</em> directing substituents.
Aryl sulfonic acids are easily synthesized by an electrophilic substitution reaction aromatic using <u>sulfur trioxide as an electrophile</u> (very reactive).
The reaction occurs in three steps:
- The attack on the electrophile forms the sigma complex.
- The loss of a proton regenerates an aromatic ring.
- The sulfonate group can be protonated in the presence of a strong acid (H₂SO₄).
Normally, a mixture of <em>ortho-para</em> substituted products would be obtained. However, since both <em>para</em> positions are occupied, only the <em>ortho </em>substituted product is obtained here.
