Question

In which of the following compounds the carbon marked with asterisk is expected to have greatest positive charge? (A)  overset*C —CH2—Cl (B) *CH3 —CH2—Mg+Cl- (C)  overset*CH3 —CH2 —Br (D)  overset*CH3 —CH2 —CH3

As Cl is most electronegative element among Cl, Mg, Br and C thus, it has greater - I effect and the asterisk marked carbon in *CH3— CH2— Cl is expected to have greater positive charge.

Q. In which of the following compounds the carbon marked with asterisk is expected to have greatest positive charge?

$C * — C H_{2} — Cl$

$^{*} C H_{3} — C H_{2} — M g^{+} C l^{-}$

$C * H_{3} — C H_{2} — B r$

$C * H_{3} — C H_{2} — C H_{3}$

As $Cl$ is most electronegative element among $Cl, M g, B r$ and $C$ thus, it has greater - $I$ effect and the asterisk marked carbon in $^{*} C H_{3} — C H_{2} — Cl$ is expected to have greater positive charge.

Q. In which of the following compounds the carbon marked with asterisk is expected to have greatest positive charge?

C∗—CH2​—Cl

∗CH3​—CH2​—Mg+Cl−

C∗H3​—CH2​—Br

C∗H3​—CH2​—CH3​

As Cl is most electronegative element among Cl,Mg,Br and C thus, it has greater - I effect and the asterisk marked carbon in ∗CH3​—CH2​—Cl is expected to have greater positive charge.

$C * — C H_{2} — Cl$

$^{*} C H_{3} — C H_{2} — M g^{+} C l^{-}$

$C * H_{3} — C H_{2} — B r$

$C * H_{3} — C H_{2} — C H_{3}$

As $Cl$ is most electronegative element among $Cl, M g, B r$ and $C$ thus, it has greater - $I$ effect and the asterisk marked carbon in $^{*} C H_{3} — C H_{2} — Cl$ is expected to have greater positive charge.
