Which of the following statements is `//` are correct ?A. `(I)` and `(IV)` are meso`-` compounds.B. `(II)` and `(III)` are enantiomers.C. `(I)` is very slow `(` or does not react `)` with alc. `KOH` in an `E2` reaction to give alkene.D. `(IV)` is very slow `(` or does not react `)` with alc. `KOH` in an `E2` raction to give alkene. |

Answer» Correct Answer - a,b,c Iosmer `(I)` is slow to react in an `E2` reaction because in its more stable conformation, all the broming atoms are in equatorial position and an anti`-` periplanar transition state cannot be achieved, `i.e.` in isomer `(I)` there is not even a single `H` and `Cl` in anti`-` positoin for elimination reaction to occur. |
