No, chiral and achiral are the opposite of each other. Achiral means a compound is superimposable on its mirror image, chiral means it isn't, so it can't be both.
achiral
achiral isusually contain aplane of symmetry
it is a chiral molecule as all groups attached to it are different
There is only 1 chiral center in 2,6-dimethyloctane. At first glance it may appear that there are two, but in the case of the second carbon in the compound, it is bound to methyl groups, making it achiral.
racemic mixture
achiral
Achiral
Glucose is a Chiral molecule having 4 chiral carbons.

racemic mixture
Yes, it is chiral
Yes, there is a methyl group attached to the number 2 carbon as well as hydrogen, bromine and a hexyl group. All that is required for chirality about a carbon atom is that there be four different groups attached. This requirement is fulfilled in 2-bromooctane.
Anthracene is not chiral, if you draw a mirror image of the molecule you find that it is superimposable. All chiral compounds must have an enantiomer which is an identical compound that is nonsuperimposable. And maleic anhydride is superimposable as well so therefore it isn't chiral. (If I assume you're referring to a Diels-Alder reaction then you'd probably like to know the answer to this as well.)
Put the molecule on a mirror, drawing the two imagees If you try to superpose each other, they are nonsuperposable That means they are not the same molecule and they are chiral. If you look for the assimetric carbon you can realize that the four substituents are different: C*-Br C*-H C*-CH2CH3 C*-CH3 Always you find an ASSIMETRIC CARBON* molecule is Chiral
A chiral compound is one that comes in mirror image forms that can't be superimposed by simple rotation and/or translation. The best example of something in everyday life that's chiral is your hands: if you try to superimpose them, either the thumb sticks out the wrong side or the palm faces the wrong way.
