Concept explainers
(a)
Interpretation:
Whether the given reaction proceeds via the SN2 or SN1 pathway must be determined, and a complete mechanism must be drawn.
Concept Introduction :
In the SN2 reaction backside attack of nucleophile takes place which leads to the inversion of configuration.
(b)
Interpretation:
Expected rate equation for SN2 reaction must be given.
Concept Introduction :
The SN2 reaction takes place in single step. So, bond breaking and new bond formation takes place simultaneously.
(c)
Interpretation:
Whether the reaction will proceed at a faster rate if cyanide concentration is doubled must be explained.
Concept Introduction :
The SN2
(d)
Interpretation:
An energy diagram must be drawn for SN2 process.
Concept Introduction:
Energy diagram of a reaction represents the relative energy level for reactants, products, transition state, and intermediate if involved.
