Which of the following statements is/are correct for the given reacti...
Statement a: The reaction is catalyzed by sulfuric acid.
Explanation:
Sulfuric acid (H2SO4) is a strong acid and can act as a catalyst in many reactions, including the conversion of alcohols to alkyl halides. In this reaction, sulfuric acid can protonate the alcohol (R-OH) to form a more reactive intermediate, which can then react with the halogen acid (HX) to form the alkyl halide (RX). Therefore, statement a is correct.
Statement b: No rearrangement of alkyl groups occur with any type of alcohol.
Explanation:
Rearrangement of alkyl groups can occur during the conversion of alcohols to alkyl halides, especially in the presence of acid catalysts. However, the given reaction does not involve any acid catalyst, so no rearrangement of alkyl groups would occur. Therefore, statement b is correct.
Statement c: The order of reactivity towards HX is 3o > 2o > 1o > CH3.
Explanation:
In general, the reactivity of alcohols towards HX follows the order of 3o > 2o > 1o > CH3, where 3o refers to tertiary alcohols, 2o refers to secondary alcohols, 1o refers to primary alcohols, and CH3 refers to methyl alcohol. This is because the stability of the carbocation intermediate formed during the reaction increases with increasing substitution of the alcohol. Therefore, statement c is correct.
Statement d: The reactivity of halogen hydracids decreases as Hl > HBr > HCl.
Explanation:
The reactivity of halogen acids (HX) towards alcohols decreases as the size of the halogen atom increases. This is because larger halogen atoms have more electron density and are less polarizable, making it harder for them to interact with the alcohol and facilitate the reaction. Therefore, the reactivity follows the order Hl > HBr > HCl. Therefore, statement d is correct.
In conclusion, both statements a and d are correct for the given reaction.
Explanation:
Sulfuric acid (H2SO4) is a strong acid and can act as a catalyst in many reactions, including the conversion of alcohols to alkyl halides. In this reaction, sulfuric acid can protonate the alcohol (R-OH) to form a more reactive intermediate, which can then react with the halogen acid (HX) to form the alkyl halide (RX). Therefore, statement a is correct.
Statement b: No rearrangement of alkyl groups occur with any type of alcohol.
Explanation:
Rearrangement of alkyl groups can occur during the conversion of alcohols to alkyl halides, especially in the presence of acid catalysts. However, the given reaction does not involve any acid catalyst, so no rearrangement of alkyl groups would occur. Therefore, statement b is correct.
Statement c: The order of reactivity towards HX is 3o > 2o > 1o > CH3.
Explanation:
In general, the reactivity of alcohols towards HX follows the order of 3o > 2o > 1o > CH3, where 3o refers to tertiary alcohols, 2o refers to secondary alcohols, 1o refers to primary alcohols, and CH3 refers to methyl alcohol. This is because the stability of the carbocation intermediate formed during the reaction increases with increasing substitution of the alcohol. Therefore, statement c is correct.
Statement d: The reactivity of halogen hydracids decreases as Hl > HBr > HCl.
Explanation:
The reactivity of halogen acids (HX) towards alcohols decreases as the size of the halogen atom increases. This is because larger halogen atoms have more electron density and are less polarizable, making it harder for them to interact with the alcohol and facilitate the reaction. Therefore, the reactivity follows the order Hl > HBr > HCl. Therefore, statement d is correct.
In conclusion, both statements a and d are correct for the given reaction.

Which of the following statements is/are correct for the given reacti...
(1) Even though the aqueous hydrogen halides are themselves strong acids, the presence of additional sulphuric acid speeds up the formation of alkyl halides.
So, option (1) is correct.
(2) The rearrangement of alkyl groups occurs, except with most primary alcohols.
So, option (2) is wrong.
(3) The order of reactivity of alcohols towards HX is 30 > 20 > 10 < />3. The reactivity decreases through a minimum at 10 and rises again at CH3.
So, option (3) is also wrong.
(4) The order of reactivity decreases in the order Hl > HBr > HCl.
So, option (4) is correct.
