Assertion: Vinyl halides do not undergo substitution reaction. Reason: Although the cation is stablished by loosely bound `pi`-electron cloud, it least occurs due to high bond strength.
A
Both (A) and (R) are wrong statements Both (A) and (R) are correct
B
statements and (R) is the correct explanation of (A) Both (A) and (R) are correct
C
statement but (R) is not the correct explanation of (A).
D
(A) is a correct statement but (R) is wrong statement.
Assertion: Aryl halides undergo nucleophilic substitution reactions with ease. Reason:The carbon halogen bond in aryl halides has partial double bonds character.
Assertion: Benzene does not give electrophilic substition reactions. Reason: Benzene ring has extraordinarily stability because of delocalisation of six pi -electrons of three double bonds.
Given below are two statements, one is labelled as Assertion (A) and other is labelled as Reason (R). Assertion (R) : Gabriel phthalimide synthesis cannot be used to prepare aromatic primary amines. Reason : Aryl halides do not undergo nucleophilic substitution reaction. In the light of the above statements, choose the correct answer from the options given below
Assertion: Aryl undergoes nucleophilic substitution with ease Reason The carbon halogen bond in aryl halides has partial double bond character .
Which of the following types of reactions occurs when a substituent has got a double bond with evenly distributed pi electron cloud?
