Among the following four structures I to IV
I `{:(" "CH_(3)),(" "|),(C_(2)H_(5)-CH-C_(3)H_(7)):}`
II `{:(" "O" "CH_(3)),(" || |"),(CH_(3)-C-CH-C_(2)H_(5)):}`
III `H-undersetHunderset|oversetHoverset|(C^(oplus))`
IV `overset(CH_(3))overset(|)underset(C_(2)H_(5)-CH-C_(2)H_(5)` it is true that

Options

A. all four are chiral compounds
B. I and II are chiral compounds
C. III is a chiral compound
D. only II and IV are chiral compounds

Answer

B

Explanation

Chiral compounds have atleast one chiral centre.ei.,e all tour atoms or groups attached to carbon are different.
