Answer: option a and d
Explanation:
Option A- Benzene undergoes substitution reaction
Example : benzene reacts with chlorine to form chlorobenzene, in the presence of Iron
(iii) chloride as a catalyst
C6H6 + Cl2 ---> C6H5Cl + HCl
Option D- Benzene also undergoes addition reaction
Example: benzene reacts with hydrogen , in the presence of nickel as a catalyst to form
cyclohexane
C6H6 + 3H2 ---> C6H12
Reasons why Option B isn't the answer
Although benzeme has degree of unsaturation but it's not five degree of unsaturation.
Benzene has 6 carbon atoms and 4 degrees of unsaturation (1 ring and 3 double
bonds).
If you work backwards and double the degrees of unsaturation you have 8 degrees of
unsaturation instead of 5.
Option C - Benzene isn't a saturated hydrocarbon
Answer:
longitudinal
Explanation:
the wave travels in the same direction as the movement from the person
Answer:functional group (top row); sources in nature (bottom row)
Explanation:
The right answer for the question that is being asked and shown above is that: "d. does not produce energy in nuclear power plants." The model most likely represents a reaction which d. does not produce energy in nuclear power plants<span>

Answer:
Change in enthalpy for the reaction is -536 kJ
Explanation:
- Overall chemical reaction can be represented a summation of two given elementary steps with slight modification.
- Take reaction (1a) and divide stoichiometric coefficients by 2
- Take reverse reaction (2a) and divide stoichiometric coefficient by 2
- Then add these two modified elementary steps to get overall chemical reaction
is an additive property. hence value of will be changed in accordance with modification
