Which of the following is a chiral molecule?
1
2
3
4
Explanation:
Substituted allenes of the general formula, $\mathrm{abC}=\mathrm{C}=\mathrm{Cab}$ or $\mathrm{abC}=\mathrm{C}+\mathrm{Cde}$ are chiral molecules. The molecule dose not a have plan or center of symmetry and hence is chiral, i.e., its mirror image is non superimposible and thus shows enantiomerism.

A compound with molecular formula $\mathrm{C}_{7} \mathrm{H}_{16}$ shows optical isomerism. The compound will be
1 2,3-dimethylpentane
2 2, 2-dimethylpentane
3 2- methylhexane
4 None of the above
Explanation:
(A): Compound with molecular formula $\mathrm{C}_{7} \mathrm{H}_{16}$ shows optical isomerism. The compound will be 2, 3dimethylpentane, because one chiral carbon is present.
