The correct relative rate of reaction of the given alkenes for any given electrophiles is

The relative rate of catalytic hydrogenation of the following alkenes is :

The correct rate of reaction of given compounds towards electrophilic aromatic substitution reaction is

The correct rate of reaction of given compounds towards electrophilic aromatic substitution reaction is

The hydration of alkenes in the presence of acids proceed via carbocation mechanisms as given below: and that carbocation is formed which is most stable, It is observed that alkenes are more reactive than alkynes towards any electrophile. This reaction, i.e., the electrophilic addition reaction of alkenes and alkynes with symmetrical addendum This shows that all reactions of alkenes and alkynes for electrophilic addition reactions may either take place via intermediates of transition state.

The influence of temperature on the rate of reaction is given by :
