MCQ
Which of the following is expected to be optically active
  • A
    ${(C{H_3})_4}C$
  • ${C_2}{H_5}CH(C{H_3}){C_3}{H_7}$
  • C
    ${({C_2}{H_5})_2}CHC{H_3}$
  • D
    $C{H_3}CH = CHC{H_3}$

Answer

Correct option: B.
${C_2}{H_5}CH(C{H_3}){C_3}{H_7}$
b
As all the four substituents attached are different. So it is chiral and hence optical active.

Which of the following complex represent maximum stability ?
Given below are two statements :
Statement(I) : Experimentally determined oxygen-oxygen bond lengths in the $O _3$ are found to be same and the bond length is greater than that of a $O = O$ (double bond) but less than that of a single ( $O - O$ ) bond.
Statement (II) : The strong lone pair-lone pair repulsion between oxygen atoms is solely responsible for the fact that the bond length in ozone is smaller than that of a double bond $( O = O )$ but more than that of a single bond $( O - O )$.
In the light of the above statements, choose the correct answer from the options given below:
