Concept explainers
(a)
Interpretation: The diagram for comparison of reactions of bromine radical with primary and secondary hydrogens of propane needs to be drawn.
Concept Introduction: The primary hydrogen atom in an
(b)
Interpretation: The transition state which is early and which is late needs to be identified.
Concept Introduction: The primary hydrogen atom in an alkane is the atom bonded to the terminal carbon atom. Whereas, the secondary hydrogen atom is hydrogen atom bonded to the central or non-terminal carbon atoms in an alkane.
(c)
Interpretation: The transition state in case of bromine radical will show a greater or lesser radical character than the chlorine radical needs to be determined.
Concept Introduction: The primary hydrogen atom in an alkane is the atom bonded to the terminal carbon atom. Whereas, the secondary hydrogen atom is hydrogen atom bonded to the central or non-terminal carbon atoms in an alkane.
(d)
Interpretation: Whether the answer in part (c) is consistent with the selectivity difference between the reaction of chloride and bromide radical and propane or not needs to be explained.
Concept Introduction: The primary hydrogen atom in an alkane is the atom bonded to the terminal carbon atom. Whereas, the secondary hydrogen atom is hydrogen atom bonded to the central or non-terminal carbon atoms in an alkane.

- I have a 2 mil plastic film that degrades after 22 days at 88C and at 61C takes 153 days. What is the failure at 47C in days.arrow_forwardIf a 5 film plastic film degraded in 30 days at 35C and the same film degraded in 10 days at 55 C and 2 days at 65C what would the predicted life time be at 22C for the same film?arrow_forwardno Ai walkthroughsarrow_forward
