Tertiary alkyl radicals are more stable than primary alkyl radicals because they have more hyperconjugation interactions with adjacent carbon-hydrogen bonds that can delocalize the radical's charge, stabilizing it. In addition, tertiary alkyl radicals are surrounded by more alkyl groups, which provide steric hindrance and shield the radical from reacting with other molecules.

Why tertiary alkyl halides are more reactive than primary alkyle halide?
Tertiary alkyl halides are more reactive than primary alkyl halides because the carbon in a tertiary alkyl halide is more substitued and more stable due to hyperconjugation and steric hindrance. This makes the C-X bond weaker in tertiary alkyl halides, making them more reactive towards nucleophilic substitution reactions.
Why tertiary carbonium ions are more stable than the primary and secondary carbonium ions?
Tertiary carbonium ions are more stable because they have more neighboring alkyl groups that can donate electron density through hyperconjugation, stabilizing the positive charge. In contrast, primary and secondary carbonium ions have fewer alkyl groups available for stabilization, making them less stable.
How can one determine the classification of alkyl halides as primary, secondary, or tertiary?
Alkyl halides can be classified as primary, secondary, or tertiary based on the number of carbon atoms directly bonded to the carbon atom that is attached to the halogen. In a primary alkyl halide, there is one carbon atom bonded to the carbon-halogen bond. In a secondary alkyl halide, there are two carbon atoms bonded to the carbon-halogen bond. In a tertiary alkyl halide, there are three carbon atoms bonded to the carbon-halogen bond.
Which carbocation is the most stable?
The most stable carbocation is the tertiary carbocation, which has three alkyl groups attached to the positively charged carbon atom.
Why tertiary carbocation is more stable?
Tertiary carbocations are more stable than primary or secondary carbocations due to the increased electron-releasing effect of alkyl groups attached to the positively charged carbon atom. This electron donation disperses the positive charge, stabilizing the carbocation through hyperconjugation and inductive effects. The greater number of alkyl groups surrounding the carbocation in a tertiary position also provides more steric hindrance, further helping to stabilize the carbocation by reducing the availability of nucleophiles to attack.

How we arrange the compounds of increasing reactivity towards SN1 hydrolysis reaction?
Compounds with more stable carbocations are more reactive towards SN1 hydrolysis. This typically follows the order: tertiary > secondary > primary alkyl halides. For example, tertiary alkyl halides will react faster in SN1 hydrolysis compared to primary alkyl halides due to the stability of the carbocation intermediate.
Why tertiary alkyl halides do not undergo wurtz reaction?
Tertiary alkyl halides do not undergo the Wurtz reaction because they do not have any active hydrogen atoms that can participate in the radical coupling step. Without an active hydrogen, the radical mechanism required for the Wurtz reaction cannot proceed.

What is the correct increasing order of reactivity for sn2 reactions?
The correct increasing order of reactivity for SN2 reactions is primary < secondary < tertiary. Primary alkyl halides are the most reactive towards SN2 reactions due to less steric hindrance, while tertiary alkyl halides are the least reactive due to increased steric hindrance.
What is the hybridization of an alkyl free radical?
the hybrdization of allyl radical carbon is sp2 which overlaps with the p orbitals of the alkene
Why primary alkyl halides show sn2 mechanism?
Primary alkyl halides favor SN2 mechanisms because they have less steric hindrance compared to secondary or tertiary alkyl halides. The SN2 mechanism involves a single-step backside attack of the nucleophile on the electrophilic carbon, requiring good nucleophile and leaving group properties. Additionally, primary alkyl halides have better leaving groups, such as halides, which further favor the SN2 reaction pathway.
How will be the structure of ch5 carbocations look like?
The structure of a tertiary carbocation in Chapter 5 would have three alkyl groups bonded to the positively charged carbon atom. This arrangement provides stability due to the electron-donating inductive effect of the alkyl groups. The positive charge on the carbon atom is offset by the electron density from the adjacent alkyl groups, making this carbocation more stable compared to primary or secondary carbocations.
What is the formula for tertiary amine?
A tertiary amine is a type of amine, which is an organic compound derived from ammonia. The formula for a tertiary amine is R3N.
