Acetaldehyde reacts with

A

Electrophiles only

B

Nucleophiles only

C

Free radicals only

D

Both electrophiles and nucleophiles

Text Solution

Verified by Experts

The correct Answer is:
B
Because carbonyl groups are strongly polarized : partially positive at the carbon end, partially negative at the oxygen end, carbon end is able to attract nucleophiles.

Acetaldehyde react with HCN :

STATEMENT -I : Acetaldehyde react with nitromethane in presence of dil . NaOH to give 1- nitro -2 propanol STATEMENT -2 : The hydrogen atom of acetaldehyde s more acidic then nitromethene.

Assertion (A): The reaction of 1 mol each of (MeCH==O) with glycerol (overset(1)underset(OH)underset(|)CH_(2)-overset(2)underset(OH)underset(|)CH-overset(3)underset(OH)underset(|)CH_(2)) gives six separable isomers. Reason (R ): Acetaldehydes react with 1-and 2-OH group of glycerol to form five-membered cyclic acetal. In the ring closure, two chiral centres are formed and thus we have pairs of enantiomers: cis and trans. When acetaldehydes react with 1-and 3-OH groups, a six membered cyclic acetal is formed giving two disatereomeric products (cis and trans). These diastereomers are achiral.

When acetaldehyde is reacted with very dilute sodium hydroxide, ____________ is obtained.
