Chlorination of 2,4-dimethylpentane via radical halogenation leads to the formation of all three of the below products. Estimate the relative percentages of each product that will be formed using this means of halogenation. Presume that 1 equivalent of chlorine is used.
Explanation / Answer
9.41
Part A
g1/g2=(r2/r1)^2
r2=(g1/g2)^0.5*r1
g1/g2=(100/99.7)
Height above earth=r2=6371[(100/99.7)^0.5 - 1]=9.57 km
Part B
r2=(g1/g2)^0.5*r1
g2=0.7g1
g1/g2=(100/97)
Height above earth=r2=6371[(100/97)^0.5 - 1]=97.77 km
Part C
r2=(g1/g2)^0.5*r1
g2=0.7g1
g1/g2=(100/70)
Height above earth=r2=6371[(100/70)^0.5 - 1]=1243.8 km
