1.	Assertion : SN_(2) reaction of an optically active aryl halide with an aqueous solution of KOH always gives an alcohol with opposite sign of rotation. Reason : S_(N)reactionsalways proceed with inversion of configuration.
Answer» Assertionis CORRECT, REASON is correct, reason is a correct explanation for assertion. Assertionis correct, reason is correct, reasonis not a correct explanation for assertion Assertionis correct, reasonis incorrect Assertion is incorrect, reasonis correct. Solution :Assertion is false, because aryl halides do not undergo NUCLEOPHILIC substitution under ordinary conditions. This is due to resonance, because of which the carbon– chlorinebondacquirespartialdoublebond character, HENCE it becomes SHORTER and stronger and thus cannot be replaced by nucleophiles.However Reason istrue.
