An alkane with one or more attached alkyl groups is called a branched alkane. Branched alkanes have alkyl groups (such as methyl, ethyl, etc.) branching off the main carbon chain, which can affect their physical and chemical properties compared to straight-chain alkanes.

What class of molecules contain the group NH2?
Amines are a class of molecules that contain the NH2 group. They are organic compounds derived from ammonia in which one or more hydrogen atoms are replaced by alkyl or aryl groups. Amines can be primary, secondary, or tertiary depending on the number of alkyl or aryl groups attached to the nitrogen atom.
Why tertiary alkyl radical more stable than primary?
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 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 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.
Why is formaldehyde is more reactive than acetaldehyde?
Formaldehyde is more reactive than acetaldehyde because it has a higher electrophilicity due to the lack of alkyl groups providing steric hindrance. This makes formaldehyde a better electrophile and more prone to reacting with nucleophiles compared to acetaldehyde. Additionally, the lack of alkyl groups in formaldehyde results in a greater stabilization of the transition state during reactions.
What is an alkane in which a halogen atom replaces one or more hydrogen atoms on a carbon chain?
halo alkane or alkyl halides
How does the size of the alkyl group in an alcohol affect the vigor of its reaction with sodium metal?
The size of the alkyl group in an alcohol can affect the vigor of its reaction with sodium metal. Alcohols with larger alkyl groups tend to react more slowly with sodium metal compared to alcohols with smaller alkyl groups. This is because steric hindrance from the bulky alkyl groups makes it more difficult for the alcohol molecule to approach and react with the sodium metal surface.
What class of molecules contain the group NH2?
Amines are a class of molecules that contain the NH2 group. They are organic compounds derived from ammonia in which one or more hydrogen atoms are replaced by alkyl or aryl groups.

What is an amine?
An amine is a derivative of ammonia where one or more hydrogen atoms are replaced by alkyl or aryl groups. Amines are classified as primary, secondary, or tertiary based on the number of alkyl or aryl groups attached to the nitrogen atom. They are important organic compounds with various roles in biological systems and industrial applications.
What is an alkylbenzene?
An alkylbenzene is a hydrocarbon formally derived from benzene by replacing one or more hydrogen atoms with alkyl groups.
In cross aldol condensation between aldehyde and ketone why aldehyde is always an electrophile?
In a cross aldol condensation between an aldehyde and a ketone, the aldehyde is always the electrophile because it has a reactive carbonyl carbon that is more electrophilic compared to the carbonyl carbon of the ketone. This is due to the presence of the less electron-donating substituent (hydrogen) attached to the carbonyl carbon of the aldehyde.
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.
What is an aralkyl?
An aralkyl is a univalent radical derived from an alkyl radical by replacing one or more hydrogen atoms by aryl groups.

Is a shorter alkane molecule more flammable?
Yes, shorter alkane molecules are generally more flammable compared to longer alkane molecules. This is because shorter alkane molecules have a higher vapor pressure, which allows them to vaporize more easily and ignite at lower temperatures.
