Total number of stereo isomers possible for the given structure
1 3
2 4
3 2
4 8
Explanation:
The number of stereocentres in this compound is \({\mathrm{\mathrm{n}=3}}\). So, No. of stereoisomers \({\mathrm{=2^{\mathrm{n}}=2^{3}=8}}\) So, the correct option is (4).

Assertion : Butene- 2 exists in two isomeric forms but butene-1 does not. Reason : But-2-ene and But-1-ene are position isomers.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
In but-2-ene, carbon atoms involved in double bond have two different groups or atoms and thus shows geometrical isomerism. But-1-ene has two similar groups on terminal C-atom.
