Question

The order of reactivity of hydrogen halides with ether is as follows.

विकल्प

• HBr > Hl > HCl

• HCl > HBr > Hl

• HCl > HBr > Hl

• HCl > HI > HBr

Answer 1

HCl > HBr > Hl

Explanation:

The cleavage of ethers usually takes place with conc. HI or HBr at high temperature.

Greater the nucleophilicity of halide ion, more is the reactivity of hydrogen halide.
