MCQ
Most stable carbocation is
  • A
    $C{H_3} - \mathop C\limits^ \oplus  {H_2}$
  • B
    $Ph - \mathop C\limits^ \oplus  {H_2}$
  • C
    $\mathop C\limits^ \oplus  {H_2}C{H_2}Cl$
  • ✓
    $\mathop C\limits^ \oplus  {H_2} - OC{H_3}$
✓

Answer

Correct option: D.
$\mathop C\limits^ \oplus  {H_2} - OC{H_3}$
d
$(1)$ and $(3)$ are not resonance stable. $(2)$ and $(4)$ are resonance stable, but $(4)$ is more stable because octet is complete.
