Given below are two statements:
Statement-I: Tertiary alkyl halides are more reactive than 1º alkyl halides towards elimination.
Statement-II: Secondary alkyl halides are more reactive than primary alkyl halides towards hydrolysis.
Both statement (I) and statement (II) are correct
Both statement (I) and statement (II) are incorrect
Statement (I) is correct but statement (II) is incorrect
Statement (I) is incorrect but statement (II) is correct
C. Statement (I) is correct but statement (II) is incorrect
Solution
Statement-I is correct because tertiary alkyl halides are more reactive in elimination reactions due to the greater stability of tertiary carbocations (E1) and more stable transition states (E2). Statement-II is incorrect because while secondary alkyl halides are more reactive in SN1 hydrolysis, primary alkyl halides are more reactive in SN2 hydrolysis due to less steric hindrance. Since hydrolysis can occur via SN2, the statement is not universally true.
