The reactants that will form products will be 
.
<h3>Activity series</h3>
Elements at higher positions in the activity series will be able to displace those in lower positions in solutions.
Thus:
because Br is higher than I in the activity series.
Cl cannot displace F in 
because F is higher than Cl in the activity series.
Also, Cl is higher than Br in the activity series, thus, the reaction 
cannot form products.
I cannot displace F, thus, 
cannot form products.

Answer:
age = 63.2 years
Explanation:
Given data
Number of years = 31
number of seconds = 1 billion
Age = ?
Solution
First we convert seconds to minutes
minutes = 1000000000 / 60
minutes = 16666666.667
Now convert minutes to hours
hours = 16666666.667 / 60
hours = 277777.778
Now convert hours to days
days = 277777.778 / 24
days = 11574.074
Now convert days to months
months = 11574.074 / 30
months = 385.802
Now convert months to years
years = 385.803 / 12
years = 32.15
Now add these years with given years
age = 31 + 32.15
age = 63.2 years
The major alkene product that results when n,n-dimethylhexan-2-amine undergoes cope elimination is hexene or hex-1-ene.
The reaction in which an amine is oxidize to an intermediate called an N-oxide which , when heated , acts as base in an intramolecular elimination reaction. The oxidation of tertiary amine into N-oxide is called cope reaction.
This elimination gives the less substituted alkene along with more substituted alkene which is Zaitsev product.
Example: Cope elimination of n,n-dimethylhexan-2-amine form hexene.
