What would substitution reaction looks like compairing to an
elimination reaction is GC analysis? And what are the possible
reasons that we might not see substitution in the GC analysis but
only see Elimination reaction.
Give the substitution and elimination products you would except
from the following reactions
(a)3-bromo-3-ethylpentane heated in methanol
(b) 1-iodo-1-methylcyclopentane heated in ethanol
(c) 3-bromo-2,2-dimethylbutane heated in ethanol
Solve the system using either Gaussian elimination with
back-substitution or Gauss-Jordan elimination. (If there is no
solution, enter NO SOLUTION. If the system has an infinite number
of solutions, express x, y, z, and
w in terms of the parameters t and
s.)
