Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion: Alkyl halides form alkenes when heated above300∘C.
Reason: CH3CH2I react slowly with strong base when compared to CD3CH2I.
Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion: 
is less reactive
than towards reactions.
Reason: Tertiary alkyl halides react predominantly by SN1 mechanism.
is more reactive than 
because the former is a tertiary alkyl halide and the latter is a secondary alkyl halide. Tertiary alkyl halides react predominantly by SN1 mechanism.Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion: Aryl halides undergo electrophilic substitutions more readily than benzene.
Reason: Aryl halide gives a mixture of o- and p- products.
Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion: Optically active 2-iodobutane on treatment with NaI in acetone undergoes racemization.
Reason: Repeated Walden inversions on the reactant and its product eventually gives a racemic mixture.
