Answer:
2. 14
Explanation:
To form Br₂ bond, a total of 14 electrons are needed. 
Bromine is an element in the 7th group on the periodic table. It has 7 valence electrons. 
- In forming the bromine gas, the two atoms of bromine shares 7 electrons each. 
- These electrons are from their outermost shell. 
- The outermost shell is the valence shell. 
- So, two atoms donating 7 electrons gives 14 electrons. 
 
        
             
        
        
        
Answer: -
Following are five examples of structures with the chemical formula C₆H₁₂
Compound A is Hexene.
Compound B is 2-Hexene.
Compound C is 3-Hexene.
Compound D is Cyclohexane.
Compound E is Methylcyclopentane.
As we can see Hexene, 2- Hexene and 3-Hexene all have double bonds.
Cyclohexane and Methylcyclopentane contains a ring.
