<h2>Answer : Option B) Hydrogen</h2><h3>Explanation :</h3>
All fossil fuels contains hydrocarbons in it. Amongst the given options hydrogen is the correct answer. Except that it contains carbon in it. Hydrocarbons are those class of compounds which contains hydrogen and carbon as element in it.
They are considered to be good fuels because they naturally bring out complete combustion as they contain hydrogen and carbon in its compound form.
Answer:
Valence Electrons are transferred/exchanged
Explanation:
CH₃CH₃ + Cl₂ → CH₃CH₂Cl + HCl
- This reaction take place in the presence of light/UV rays. (i.e, photochemical reaction)
- It's a Chlorination reaction because here there's addition of chlorine.
- It's a substitution reaction because Cl substituted H from place and attach there.
Option which is NOT correct is
Option A (It's not an elimination reaction)
Therefore,
Option A is correct✔
Answer:
True
Explanation:
Aromatic compounds undergo substitution rather than addition reactions because the aromatic structure is maintained.
Electrophilic aromatic substitution begins with attack of the electrophile on the aromatic ring to yield a delocalized intermediate called the arenium intermediate. Loss of hydrogen from this intermediate yields the final product.
