Answer:
1
Explanation:
Oxygen is a pure substance therefore it is only made up of one kind of atom
Answer:
Option A.
Explanation:
To know which structure is correct, let us name both compound.
In naming the above organic compound, the following must be observed:
1. Locate the functional group. In this case it alkene since it has carbon to carbon double bond (C=C).
2. Locate the longest continuous carbon chain. In this case the compound is a cyclic compound with 6 carbon i.e cyclohexene.
3. Locate the substituents attached to the compound. In this case, bromine (bromo) and chlorine (chloro) are the substituents attached.
4. Locate the position of the substituents and name alphabetically counting from the double bond. In this case, bromo comes before chloro
5. Combine the above to get the name.
For option A, the name is:
4–bromo–5–chlorocyclohexene.
For option B, the name is:
3–bromo–4–chlorocyclohexene.
We can see that Option A gives the correct structure of the compound.
Most common mineral acids solutions (HCl, H2SO4, HNO3, H3PO4, etc.) are prepared in water. Infact, system is<span> acidic only in aqueous medium.

However, in few cases, it isn't advisable/viable to perform reaction is aqueous medium. This can be due to poor solubility of reactant in water. This situation arises especially, if reactant is highly non-polar in nature.
There also exist a possibility that, reactant is not stable in aqueous medium. In such event, use of water has to be avoided.
For such reaction, solid camphorsulfonic acid is added in reaction, when acid is required to initiate/catalyst the reaction.
The major advantage that camphorsulfonic acid offers is that, it is solid and hence it is easy to weight. Also, they don't required water addition for the reaction.
Answer:
Boiling water breaks intermolecular attractions and electrolysis breaks covalent bonds.
Explanation:
When water boils, hydrogen bonds are broken between adjacent water molecules. The hydrogen bond is an intermolecular bond between adjacent oxygen and hydrogen atoms of water molecules.
During electrolysis, water dissociates in the presence of electric current. Here, ions are formed in the process. Therefore, covalent bonds are broken here.
