why HCL is not used in dehydration of alcohol

it is not because that H2SO4 is a straong acid that it is a dehydrating agent
(SO₄)⁻² is a better dehydrating agent than Cl⁻¹
so H₂SO₄ is a better dehydrating agent than HCl
hope this helps

Usually only strong acids like Sulfuric or Phosphoric acids are used to dehydrate an alcohol and produce a double bond. Why is it that a hydrogen halide (i.e HBr, HCl, HI) cannot be used to dehydrate an alcohol?
My initially thinking when using a hydrogen halide was that an alkyl halide would form along with water, but a double bond would not form.
but HCl is a stronger acid than H2SO4
No H2SO4 is more strong acid
search in google the pKa values of HCl and H2SO4 a substance less pKa is more strong acid pKa of HCl is -6.3 but pKa of H2SO4 is just -3 what do you think is less -6.3 or -3 hence it is proved that HCl is a stronger acid than H2SO4
