Assertion: Trans isomers are more stable...

Assertion: Trans isomers are more stable than cis isomers
Reason: The cis isomer is the one in which two similar group are on the same side of double bond.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true and the reason is not the correct explanations of the assertion

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
Trans isomer is more stable than cis isomer because in cis isomer, the bulky group are on the same side of the double bond. The steric repulsion of the groups makes the cis isomer less stable than the trans isomer in which the bulky groups are far apart. (They are on the opposite side of the double bond).

Which tautomer isomer is more stable :

Draw geometrical (or cis-and trans-) isomers of the following structures and give their IUPAC names. (i) C_(2)H_(5)C CH_(3)=C CH_(3)C_(2)H_(5) (ii) CH_(3)CH_(2)CH=CHCH_(2)CH_(3) Strategy: An isomer in which two identical atoms (or groups) lie on the same sides of the double bond is called as cis isomer whereas an isomers in which identical atoms ( or groups) lie on the opposite sides of the double bond is called a trans isomer.

Classify the following alkenes and their derivatives as Z or E (i) (ii) Strategy: This method is preferable to the use of cis-trans beacuse it is not practical to identify cis and trans isomers when the four groups on C=C are different. The letter Z is used when the two high-priority substituets are on the same side of the double bond and the letter E is used when they are on the opposite sides (from the German words zusammen meaning together and entgegen meaning opposite), as shown:

Cyclohexane exist as two chair conformations in rapid equilibrium at room temperature. Each carbon atom on a cyclohexane ring has one axial and one equatorial bydrogen. Rind-flipping converts axial H's to equatorial H's and vice-versa In substituted cyclohexane, groups larger than hydrogen ar more stable in the equatorial position. The cis isomers has two groups on the same side of the ring, eithere both up or both down. The trans isomer has two groups on opposite side of the ring one up and one down.
