MCQ
Which one of the following can show $+\text{I}$ effect?
  • A
    $\text{CBr}_3$
  • ✓
    $\text{CH}_3$
  • C
    $\text{CCl}_3$
  • D
    $\text{CHO}$
✓

Answer

Correct option: B.
$\text{CH}_3$
Only $\text{CH}_3$ shows $+\text{I}$ effect rest of them shows $-\text{I}$ effect, since other groups contain electronegative atom which will pull electrons towards it causing $-\text{I}$ effect.
