Answer:
Explanation:
An electrophilic addition reaction occurs when an electrophile attacks a substrate, with the end result being the inclusion of one or many comparatively straightforward molecules along with multiple bonds.
In the given question, the hydrogen bromide provides the electrophile while the bromide is the nucleophile. The mechanism proceeds with the attack of the electrophile on the carbon, followed by deprotonation. This process is continued with a formation of carbocation and the bromide(nucleophile) finally bonds to the carbocation to form a stable product.
The first diagram showcases the possible various starting molecules for the synthesis while the second diagram illustrates their mechanism.

Answer:
Chemical formula of Oxygen is O2.
We know ,
1 mole of a substance contains 6.022×10^23, Avogadro’s Constat.
Here, Molar mass of O = 16u
And molar mass of O2 = 32u
And 32g of O2 = 1 mole of O2
It means that,
32g of O2 = 6.022×10^23 molecules
