Lodide is a better nucleophile than bromide.

Text Solution

Verified by Experts

The correct Answer is:

When the nucleophilic centres are different and belong to the same group of periodic table, nucleophilicity is antiparallel to basicity.
Acidity : `Hl gt HBr`
Basicity : `I^(Ө) lt Br^(Ө)`
Nucleophilicity : `I^(Ө) gt Br^(Ө)`.
