What does “Inductive effect” actually mean in Organic Chemistry — Basic Concepts, and why does it matter for NEET?
a permanent shift of electron density through sigma bonds due to electronegativity differences.
I keep getting “Inductive effect” questions wrong in Organic Chemistry — Basic Concepts. What's the trap?
thinking the inductive effect travels undiminished along a chain.
What does “Resonance” actually mean in Organic Chemistry — Basic Concepts, and why does it matter for NEET?
delocalisation of electrons over several atoms, giving extra stability.
I keep getting “Resonance” questions wrong in Organic Chemistry — Basic Concepts. What's the trap?
believing the separate resonance structures actually exist and interconvert.
What does “Electrophiles and nucleophiles” actually mean in Organic Chemistry — Basic Concepts, and why does it matter for NEET?
electrophiles are electron-poor (seek electrons); nucleophiles are electron-rich (donate electrons).
I keep getting “Electrophiles and nucleophiles” questions wrong in Organic Chemistry — Basic Concepts. What's the trap?
swapping the two definitions.
What does “Carbocation stability” actually mean in Organic Chemistry — Basic Concepts, and why does it matter for NEET?
order 3° > 2° > 1°, because alkyl groups donate electrons and stabilise the positive charge.
I keep getting “Carbocation stability” questions wrong in Organic Chemistry — Basic Concepts. What's the trap?
ranking a primary carbocation as more stable than a tertiary one.
What is the difference between electrophile and nucleophile?
An electrophile accepts an electron pair (e.g. H⁺, NO₂⁺); a nucleophile donates one (e.g. OH⁻, NH₃).
What is the difference between inductive effect and resonance effect?
The inductive effect works through sigma bonds and fades with distance; resonance works through pi systems and can act over long conjugation.
What is the difference between SN1 reaction and SN2 reaction?
SN1 goes through a carbocation in two steps (favoured by 3° substrates); SN2 is a one-step backside attack (favoured by 1° substrates).
