Consider the following structures
(i) \(\mathrm{CH}_{2}=\stackrel{\oplus}{\mathrm{C}} \mathrm{H}\) (ii) \(\mathrm{CH}_{3}-\stackrel{\oplus}{\mathrm{C}} \mathrm{H}_{2}\)
(iii) \(\mathrm{CH}_{2}=\mathrm{CH}-\stackrel{\oplus}{\mathrm{C}} \mathrm{H}_{2}\) (iv) \(\mathrm{C}_{6} \mathrm{H}_{5}-\stackrel{\oplus}{\mathrm{C}} \mathrm{H}-\mathrm{C}_{6} \mathrm{H}_{5}\)
The correct sequence of these carbocations in the decreasing order of their stability is
(i) \(\mathrm{CH}_{2}=\stackrel{\oplus}{\mathrm{C}} \mathrm{H}\) (ii) \(\mathrm{CH}_{3}-\stackrel{\oplus}{\mathrm{C}} \mathrm{H}_{2}\)
(iii) \(\mathrm{CH}_{2}=\mathrm{CH}-\stackrel{\oplus}{\mathrm{C}} \mathrm{H}_{2}\) (iv) \(\mathrm{C}_{6} \mathrm{H}_{5}-\stackrel{\oplus}{\mathrm{C}} \mathrm{H}-\mathrm{C}_{6} \mathrm{H}_{5}\)
