Where alcoholics line up to report.
I reward the bulk with clouds so fast,
But the slim must wait—they come in last.
Tell me, who tests spirits with a death stare?

Secondary alkyl halides are borderline: they can undergo both SN1 and SN2 depending on conditions.
When sodium phenoxide is treated with isopropyl chloride (secondary alkyl halide), it will undergo this mechanism.

Citrus fruits like oranges and lemons predominantly contain d-limonene, while l-limonene is found in mint and pine. Despite being mirror images, they smell very different. Does smell have anything to do with optical activity?
Yes or No
Yes
Even though d-limonene and l-limonene have the same chemical formula, their three-dimensional shape differs due to chirality.
The olfactory receptors in our nose are also chiral and can distinguish between the two enantiomers.
Thus, d-limonene (from citrus) smells sweet and orange-like, while l-limonene (from mint or pine) smells sharp or turpentine-like.

This is C10H10 called [10] Annulene. Is this Molecule Aromatic or No?
Non Aromatic
It has 10 π-electrons → 4n + 2 = 10 → n = 2
It is cyclic, conjugated, and planar-looking in 2D drawings.
BUT
Due to steric hindrance and internal hydrogen crowding, [10]annulene cannot maintain planarity.
Lack of planarity breaks the condition for π-orbital overlap, making it non-aromatic despite satisfying Hückel’s Rule.
