Among the following four structures `I` to `IV`
`C_(2)H_(5)-overset(CH_(3))overset(|)underset((I))(CH)-C_(3)H_(7)` `CH_(3)overset(O)overset(||)(C)overset(CH_(3))overset(|)underset((II))(CHC_(2))H_(5)`
`H-overset(H)overset(|**)underset(III)underset(H)underset(|)C` `C_(2)H_(5)-overset(CH_(3))overset(|)underset((IV))(CH)-C_(2)H_(5)`
it is ture thate

A

all four are chiral compounds

B

only `II` and `IV` are chiral compounds

C

only `III` is a chiral compound

D

only `I` and `II` are chiral compounds

Text Solution

Verified by Experts

The correct Answer is:
D
`III` and `IV` are chiral due to the presence of a plane of symmetry while `I` and `II` are chural due to the presence of just one chiral carbon:
`C_(2)H_(5)-overset(H)overset(|**)underset((I))underset(H)underset(|)C-C_(3)H_(7), CH_(3)overset(O)overset(||)C-overset(CH_(3))overset(|**)underset((II))underset(H)underset(|)C-C_(2)H_(5)`
