sir please give some examples of + I EFFECTS. please answer soon as possible i need them for my exams on tuesday

+I effect may be defined group which attract electron less strongly as hydrogen. Generally may be under stood as electron repelling nature of group like methyl group.  

Stability of carbonium ions: The stability of carbonium ions increases with increase in number of alkyl groups due to their +I effect. The alkyl groups release electrons to carbon, bearing positive charge and thus stabilize the ion.   The order of stability of carbonium ions is: 

inductive effect: stability of carbonium ions

Positive inductive effect (+I): It refers to the electron releasing nature of the groups or atoms and is denoted by +I. Following are the examples of groups in the decreasing order of their +I effect. 

C(CH3)3 > CH(CH3)2 > CH2CH3 > CH3 > H
