Answer:
Option C. 251 kJ
Explanation:
The activation energy (Ea) of a given reaction is the minimum energy that must be overcomed for reactant to proceed to product.
The activation energy (Ea) can be obtained from an energy profile diagram by simply calculating the difference between the energy of the activation complex (i.e the peak) and the energy of the reactant.
Thus, we can obtain the activation energy for the reaction above as follow:
Activation complex = 332.6 kJ
Energy of reactant = 81.6 kJ
Activation energy =?
Activation energy = Activation complex – Energy of reactant
Activation energy = 332.6 – 81.6
Activation energy = 251 kJ
Therefore, the activation energy of the reaction is 251 kJ

Answer:
H+ ----- Br-
H+ ----- Cl-
O₋₋ -----2H++
CH3 ----- O- ------ H+
Explanation:
Dipole moment occurs when there is bonding between a very strong electronegative element and hydrogen atom.
Electronegative elements are the element which attract electrons towards themselves, (that is they have strong affinity for electrons).
Generally, group 7 elements (Fluorine, Chlorine, Bromine, Iodine) of the periodic table are highly electronegative
Answer:
The correct option is A.
Explanation:
Isomers are molecules with the same formula but different structure. If you look at the previous structures and count the number of C and H, you find that A and the molecule from the question has the same number of C and H, but their structures are different.
