WebIntroduction. There are two main effects of substituents. The substituent will affect the rate of reaction (aka reactivity) of the ring, and it will also affect the position of attack (called “directing effects”) on the ring by the incoming electrophile. Thus we need to answer the following questions: Does the substituent activate or ...

Web17 Points. 13 years ago. Dear Nikhil, Since Chlorine is more electronagative than Florine, there is more inductive effect on carbon of CCl 3 (-) than in CF 3 (-) which stablises its negative charge. The negative charge on the carbon in CCl 3 (-) is further stablised in the vacant d-orbital of Chlorine which is not possible in case of CF 3 (-). rweb classesWebOrganic chemistry The alkanes form a homologous series of saturated hydrocarbons.
