When a positive ion (electrophile) attacks on a pi bond or partially negative carbon atom and replace H as a positive ion then it is electrophilic substitution reaction.
The standard definition of the Net Attendence Ratio is "number of pupils in the official age group for a given level of education who attend school in that level, expressed as a percentage of the population in that age group
Indole undergoes electrophilic substitution predominantly at the 3 position due to the resonance stabilization of the intermediate formed during the reaction. When an electrophile attacks the 3 position, the resulting cation can delocalize its positive charge over the nitrogen atom, which stabilizes the intermediate. In contrast, substitution at the 2 position does not benefit from the same level of stabilization, as the positive charge cannot be effectively delocalized onto the nitrogen. This makes the 3 position more favorable for electrophilic substitution reactions.
A bursar is the senior financial administrator at a school or university. In the United States bursars are usually at the higher education level. Other countries have it at lower levels also.
Recent graduates from high school or college usually take entry-level positions. These jobs are targeted at college graduates often offer a higher salary than those targeted at high school graduates. These positions are more likely to require specific skills and knowledge.
