well A chiral molecule is a type of molecule that lacks an internal plane of symmetry and has a non-superposable mirror image. The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom.
i know that activity Optical is possible only in chiral molecules.
can you show me one molecule from my list then i can try to deduce from it.
Chiral molecules have (at least) one assymetric carbon. That means carbon with four different substituents. Take a look at your molecules, count different groups attached to each carbon - if there is four, you have a chiral molecule.
ok i think i start to understand,
so if i correct the Chiral molecules in my list is A,C,E in my picture here is hard to see but the carbon atom in molecules c have an covalent bond with hydrogen in the left side.
the rule "Chiral molecules have (at least) one assymetric carbon. That means carbon with four different substituents" is also acceptable when there an double covalent bond like we have here when the carbon atoms have an double covalent bond with hydrogen atoms?
thank you.
OK, I will put it differently. You have a carbon with a double bond. Is it possible that it has four substituents? Take a look at the picture you have just attached - to how many atoms/groups of atoms is the carbon bonded? Four?
