Identify the following compound which exhibits geometrical isomerism
1 But-2-ene
2 But-1-ene
3 Butane
4 Iso-butane
Explanation:
The necessary and sufficient condition for a compound to exhibit geometrical isomerism is that the two groups attached to the same double bonded carbon must be different, i.e., alkenes of the following types show cis-trans isomerism. \(\mathrm{abC}=\mathrm{Cab}, \mathrm{abC}=\mathrm{Ccd}, \mathrm{abC}=\mathrm{Cax}, \mathrm{abC}=\mathrm{Cbx}\) Thus, out of the given examples, only but-2-ene exhibits geometrical isomerism.

Assertion : Addition of \(\mathrm{HBr}\) on 2-butene gives two isomeric products. Reason : Addition of \(\mathrm{HBr}\) on 2-butene follows Markownikoff's rule
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 Both Assertion and Reason are incorrect
Explanation:
As 2-butene is a symmetrical molecule, thus it does not give any isomer and also Markownikoff's rule is not applicable in this case. (applicable for unsymmetrical alkene). Hence, both Assertion and Reason are incorrect
