Multiple Choice QuestionsIn which of the following compounds, the C-Cl bond ionisation shall give most stable carbonium ions?
A single compound of the structure is
obtainable from ozonolysis of which of the following cyclic compound?
Which of the following is a correct electron displacement for a nucleophilic reaction to take place?
C.
Allylic and benzylic halides show high reactivity towards Sn1 reaction Further, due to greater stabilisation of allyl and benzyl carbocations intermediates by resonance, primary allylic and primary benzylic halides show higher reactivity in Sn1 reactions than other simple primary halides.
Hence, it undergoes nucleophilic reaction readily.
