Aromatic compound has continuous cyclic structure with( 4n+2)π electrons (Huckels rule), where n = 0,1,2…
Here number of pi electron are 6, where 4 from two double bond and 2 from nitrogen non-bonding electrons, hence it has total 6 pi electrons, therefore
6= ( 4n+2)π
4 = 4n
n =1
Hence it is an aromatic compound
Answer:
The correct answer to you your question is Potassium
Explanation:
Potassium is the most reactive
Answer:
Their identity changes in both Reaction A and Reaction B.
The fittest species for a certain biome will adapt and change so as to keep living. This process is evolution and an example can be giraffes. If they had smaller necks, they couldn't reach the tree tops where food is, so only the fittest one with large necks survived, and they evolved by having the entire species grow up with large necks.
Its d. Speed (v) and frequency(f) both stay the same.
<span>Because Amplitude does not affect wave frequency. When you put more energy into the wave (larger amplitude) it does not affect how often you repeat a cycle.
</span>Also speed can be altered when the medium changes through which it travels.
