FAQs on Super Trick For Inductive Effect - GOC-1st - +I effect & -I Effect - Chemistry For NEET AIIMS JEE Video Lecture

1. What is the concept of inductive effect in organic chemistry?
Ans. The inductive effect is a concept in organic chemistry that describes the permanent polarization of σ bonds due to the electronegativity difference between atoms. It involves the transmission of electron density through a chain of atoms, resulting in the distribution of charge and the stabilization or destabilization of neighboring atoms or groups.
2. How does the inductive effect affect the electron density in a molecule?
Ans. The inductive effect can either increase or decrease the electron density in a molecule. When a more electronegative atom is attached to a carbon chain, it can withdraw electron density towards itself, resulting in a decrease in electron density at the carbon atom (called -I effect). Conversely, when a less electronegative atom is attached to a carbon chain, it can donate electron density towards the carbon atom, increasing its electron density (called +I effect).
3. Give an example of a group that exhibits the -I effect and explain its impact on a molecule.
Ans. One example of a group that exhibits the -I effect is the nitro group (-NO2). The electronegative oxygen atoms in the nitro group withdraw electron density from the adjacent carbon atom, resulting in a decrease in electron density. This can destabilize the molecule and make it more reactive towards nucleophilic attacks.
4. How does the inductive effect influence the acidity of organic compounds?
Ans. The inductive effect can influence the acidity of organic compounds by either increasing or decreasing their acidity. Electron-withdrawing groups (-I effect) attached to an acidic functional group can stabilize the resulting negative charge, making the compound more acidic. Conversely, electron-donating groups (+I effect) can destabilize the negative charge, making the compound less acidic.
5. Can you provide an example of a compound where the inductive effect plays a significant role in its chemical behavior?
Ans. One example is the behavior of halogenated alkanes (such as chloroform or bromoethane) in nucleophilic substitution reactions. The presence of electronegative halogen atoms induces a partial positive charge on the carbon atom, making it more susceptible to nucleophilic attacks. This demonstrates the impact of the inductive effect on the reactivity of organic compounds.
