Question

Writw thw structure of an isomer of a compuond c4h9br which is most reactive towards sn1reactuon

Answer 1

there you go . the structure that you are looking for is the tertiary butyl Bromide which is a saturated branched isomer of n-butyl Bromide . when the Bromide ion is removed from the tertiary butyl group it generates the tertiary butyl cation which is SP2 hybridised and stabilized buy hyperconjugative effect buy 9 methyl hydrogens . and therefore it can undergo SN1 reactions more promptly .
