Which of the following compounds exhibits stereoisomerism?

Options

A. 2-methyl butene-1
B. 3-methyl butyne -1
C. 3-methyl butanoic acid
D. 2-methyl butanoic acid

Answer

D

Explanation

`{:(CH_(3)-CH_(2)-C=CH_(2),CH_(3)-CH-C-=CH,),(" |"" |"),(" "CH_(3)" "CH_(3)),(" "A" "B):}`
`{:(CH_(3)-CH-CH_(2)-COOH,CH_(3)-CH_(2)-overset(*)(C)H-COOH),(" |"" |"),(" "CH_(3)" "CH_(3)),(" "C" "D):}`
In D(2-methyl butanoic acid) asymmetric C-atom is present. So, it shows the property of stereoisomerism (Compound A does not show the property of geometrical isomerism)
