Which of the following is a chiral compound?

Options

A. `2,3,4-`trimethylhexane
B. `n-`hexane
C. methane
D. `n-`butane

Answer

A

Explanation

`underset(2,3,4-"trimethylhexane")(H_(3)overset(1)C-overset(CH_(3))overset(2|)underset(H)underset(|)C-overset(CH_(3))overset(3|**)underset(H)underset(|)C-overset(CH_(3))overset(4|)underset(H)underset(|)C-overset(5)CH_(2)overset(6)CH_(3))`
This compound is chiral beacuse its moelcule has two chiral carbon atoms `(C-3` and `C-4)`.
Pther molecules are chiral due to the presence of a plane of symmetry.
