Explaining the conditions for the reaction. Remember that the reaction is done by reacting the aldehyde or ketone with a solution of sodium or potassium cyanide to which enough dilute sulphuric acid is added to give a pH of around 4 - 5. Hydrogen cyanide as a very weak acid. The initial attack on the carbonyl group is by a cyanide ion.
The compound that undergoes a reaction with EtONa CH3CH2C(Br)(CH3)CH3 is CH3C = CC(CH3)2. When we predict the major organic product formed when the coumpound underoes a reaction with EtONa - CH3CH2C(Br)(CH3)CH3, the prediction will be CH3C =.

2.2 Ethanol induces a metabolic switch that enhances its utilization as a carbon source. Since SODH‐1 and ALH‐1 can transform ethanol to acetaldehyde and subsequently to acetate, we hypothesized that ethanol could penetrate the cuticle of the dauer larva and induce a switch that allows it to be used as an energy source.
Consider the following example: A mixture results because the reaction proceeds by way of a resonance stabilized radical. The regioselectivity of the addition to unsymmetrical alkenes is different from that in addition of HBr in the absence of heat, light or peroxides.
The main reactions of the carbonyl group are nucleophilic additions to the carbon‐oxygen double bond. As shown below, this addition consists of adding a nucleophile and a hydrogen across the carbon‐oxygen double bond. Due to differences in electronegativities, the carbonyl group is polarized.

Describe what a chemical equation is. synthesis reaction; double replacement, single replacement and decomposition; synthesis is two or more simple substances...1,2-pentanediol + acetone with acid as a catalyst would produce what? I'm guessing one of the alcohols in the 1,2-pentanediol will act as a nucleophile and attack the carbon of the carbonyl in the acetone after the oxygen in the acetone is protonated by the acid. I'm not sure if that's right and I don't...

more substituted carbon pattially breaks before the attack of the nucleophile. Therefore the reaction takes place at the more substituted carbon, which has developed partial positive charge during the course of the reaction.
