নিচের কোন যৌগটি cis-trans isomerism দেখাবে? (i) `(CH_(3))_2C=CH-C_(2)H_(5)`...

Which of the following compounds will show cis-trans isomerism? (i) (CH_(3))_2C=CH-C_(2)H_(5) (ii) CH_(2)=CBr_(2) (iii) C_(6)H_(5)CH=CH-CH_(3) CH_(3)CH="CC"lCH_(3)

While of the following compounds will exhibit geometrical (or cis-trans) isomerism? (i) CH_(3)CH=CHCH_(2)CH_(3) (ii) C_(6)H_(5)CH=CHCH_(3) (iii) CH_(2)=C(CH_(3))_(2) (CH_(3))_(2)C=CH-C_(2)H_(5) Strategy: Essential requirement for any alkene to exhibit geometrical isomerism is that each of the double bonded carbon atoms should be attached to two different atoms or groups of atoms: m!=n and p!=r . Notice that m and p may be same or different Similarly, n and r may be same or different.

Which of the following alkanes can exhibit cis-trans isomerism? (i) CH_(2) = CHCH_(2)CH_(3) , (ii) CH_(2) = C(CH_(3))_(2) (iii) CH_(3)CH=CHCH_(3) , (iv) CH_(3)CH_(2)CH=CHCl
