Identify the molecules of formula C5H12 that are chiral.
SOLUTION
The formula C5H12 belongs to a saturated alkane, therefore, it cannot have cycles or double bonds.
Alcohols that do not have chirality (without asymmetric carbons) are:

Chiral alcohols (have asymmetric carbons) are:

Ethers are also isomers with the formula C5H12 , but do not have chiral centers.

If you find any other isomers, post them in the stereochemistry forum.
