Chemistry · Aldehyde and Ketones: Nature of carbonyl group, nucleophilic addition to >C=O group, relative reactivities of aldehydes and ketones
Polarity of carbonyl group increase with increase of
Polarity of carbonyl group increase with increase of
- A. electronegative groups
- B. electropositive groups
- C. neutral group
- D. none of these
Step-by-step solution
The carbonyl group (C=O) has a dipole with carbon partially positive and oxygen partially negative. Adding electronegative groups near the carbonyl carbon withdraws electron density via inductive effect, increasing the partial positive charge on carbon and thus increasing the polarity. Electropositive groups donate electron density, reducing polarity, and neutral groups have no significant effect.
