IUPAC name of $CH_3CH_2CH=CHCH_3$:

Reactivity of free radical halogenation: F₂ vs Cl₂ vs Br₂:

Number of monohalogenated products of $(CH_3)_3CH$:

Saytzeff's rule applies in:

Decolorization of Baeyer's reagent indicates:

Markovnikov product of $CH_3CH=CHCH_3$ with HBr:

Terminal alkyne reacts with $AgNO_3/NH_3$ to give:

Toluene on free radical chlorination gives major:

Sulfonation of benzene is reversible because:

Hückel rule: cycloheptatrienyl cation $C_7H_7^+$ is:

Number of carbons in benzene:

$\pi$ electrons in pyridine ($C_5H_5N$):

Number of $sp^2$ carbons in benzene:

Assertion (A): Terminal alkynes are acidic in nature. Reason (R): The $\equiv C-H$ bond has 50% s-character, leading to higher acidity than $sp^3$ C-H.

Assertion (A): $-NO_2$ group is a meta director. Reason (R): $-NO_2$ is strongly electron-withdrawing; destabilizes carbocation intermediate at ortho/para positions.
