(3)(\mathrm{R}_2 \mathrm{C}=\stackrel{\ominus}{\mathrm{C}}\mathrm{H})
(4) is in the order of
(2)
(3)(\mathrm{R}_2 \mathrm{C}=\stackrel{\ominus}{\mathrm{C}}\mathrm{H})
(4) is in the order of
Options
- A(1) (2) (3) (4)
- B
- C(4) (2) (3) (1)
- D(1) (3) (2) (4)
Correct answer
A. (1) (2) (3) (4)
Step-by-step solution
Key Idea : When scharacter increases, then electrons becomes more closer to the nucleus and structure is of lower energy and is more stable. The stability order of carbanions is as :
>}_{5}^{\ominus}>}_{3}
