Q19 / 160 · TS EAMCET 2021 (05 Aug Shift 2) · Chemistry

The stability order of the given alkenes is

A
$(I) > (II) > (III)$
B
$(I) > (III) > (II)$
C
$(III) > (II) > (I)$
Correct answer
D
$(III) > (I) > (II)$

Solution

According to the question, In case of fuse ring structure, alkene which has double bond on common carbon atoms of fuse ring structure is maximum stable.
As the distance of double bond from common carbon atom is increases then stability of alkene will be decreases.
The correct order of stability of given alkene in question is (c) > (a) > (b)

Hence, the correct answer is option: 'D'.
