a)
Given
Retention time of alkane
Pentane (5 carbon atom)= 4.19, hexane (6 C)= 6.64, and heptane(7 C) =10.51
According to definition of Kovat’s retention indices for normal alkane is 100 times the number of carbon thus the retention indices are as follows
Pentane (5 carbon atom)= 100 x 5 = 500
hexane (6 C)=100 x 6 =600
heptane(7 C) =100 x 7 = 700
Add Answer to:
3. (5 pt). The adjusted retention times of pentane, hexane and heptane are 4.19, 6.64 and...
