Aldehydes and ketons are susceptible ...

Aldehydes and ketons are susceptible to nuclephlic addition because carbonylgroup
Polar (due to electronegativeity difference between carbon and oxygen
positive charge on carbonyl compound towards nucleophilic . this addition is catalysed by acid . REactivity of carbonyl compound towards nuclephilic addotion increase with increase in teh electron deficiency at carbonyl carbon Thus (-I.E ) groups increase while (+I.E ) groups decreases the reactivity of carbonyl compound .
which among the following is most reactive towards nuclephilic addition

A

`FCH_2 CHO`

B

`CICH_2 CHO`

C

`BrCH_2 CHO`

D

`ICH_2 CHO`

Text Solution

Verified by Experts

The correct Answer is:
A
Rate of nucleophilic addition depends on + ve charge on cabonly C - atom .As + ve charge increase reactivity increases ` therefore underset(F ) underset(|) CH_2 -CHO (a) `
