When 2-pentene reacts with HBr, what will be the major product?

If we consider the first step (formation of carbocation by the attack of the proton). A couple of textbooks I referred say that when the substituents on the $\ce{C=C}$ are different, the direction of ...

Does hyperconjugation into sigma-star explain methylamine's increased basicity relative to ammonia?

The inductive effect with the polarisation of the C-N bond obviously plays a role in stabilising the positive charge of the conjugate acid. But given the similar electronegativities for C and H, CH3 ...

Does an electronegative atom which carries a negative formal charge withdraw electrons by induction?

Electronegative atoms withdraw electrons by their inductuve effect. Does this fact remain true even when they are heavily loaded with electrons through negative formal charge? Are these two ideas ...

Comparing relative negative inductive effect of substituents (dialkyl amine, amine, alkoxide, fluoride)

Which of the following is correct with respect to the negative inductive effect of the substituents? 1. $\ce{-NR2 < -OR < -F}$ 2. $\ce{-NH2 < -OR < -F}$ 3. $\ce{-NR2 > -OR > -F}...

Confusions about inductive effect and acid strength

If one of the hydrogens in the alkyl side chain of ethanoic acid is replaced with an atom of Chlorine, the acid has a larger Ka value. My book says this is since the Cl "borrows" electron density from ...

Why is C2H5 a stronger +I group than CH3?

While reading about the basic character of amines, I came across a note which said that $\ce{CH3-CH2-NH2}$ was more stable than $\ce{CH3-NH2}$ as $\ce{C2H5}$ was a stronger +I group than $\ce{CH3}$. ...

Mechanism of substitution for disubstituted benzene

Here, I count the individual effects of the two oppositely directing groups. I assume that the deactivation of $\ce{NO_2}$ group at ortho and meta positions is higher. While bromination, I get the ...

Which of the 2 structures is more stable?

As far as I know, alkenes with more number of hyperconjugating structures are more stable. Hyperconjugation has a greater stablizing effect than Inductive effect. So, (d) should be more stable as it ...

Inductive effect vs electronegativity

Inductive effect is basically a group or substituent pulling electrons from neighbouring atoms giving them partial charges. Electronegativity is basically how much a certain atom tugs on the electron ...
