In cross aldol condensation between aldehyde and ketone why aldehyde is always an electrophile?
Alkyl groups are electron donating (whereas hydrogen atoms aren't). A ketone has 2 alkyl groups attached to the carbonyl carbon, but an aldehyde has only 1 alkyl group attached to its carbonyl carbon. This gives the aldehyde carbon more positive charge character, which makes it a better electrophile than the ketone. Another factor is less stearic hindrence for carbonyl carbon of aldehyde as compare to ketones.

Why is sulfuric acid used in aromatic nitration?
Sulfuric acid is used in aromatic nitration as a catalyst and as a source of protons to initiate the nitration reaction. It helps to activate the nitric acid by protonating it, making it a better electrophile. Additionally, sulfuric acid helps to absorb the water produced during the nitration process, which can improve the yield of the desired nitro compound.
What are the benefits of using triplet symbols in machine learning algorithms?
Using triplet symbols in machine learning algorithms helps improve the accuracy and efficiency of models by providing a way to compare and learn from sets of three data points. This can lead to better performance in tasks like image recognition, recommendation systems, and natural language processing.

What is the role of sulphuric acid in the synthesis of Nitro benzene?
Sulfuric acid acts as a catalyst in the synthesis of nitrobenzene by nitrating benzene. It facilitates the nitration reaction by protonating the nitric acid, making it a better electrophile for attacking the benzene ring. Sulfuric acid also helps in generating the nitronium ion, which is the active species involved in the nitration process.
Why is formaldehyde is more reactive than acetaldehyde?
Formaldehyde is more reactive than acetaldehyde because it has a higher electrophilicity due to the lack of alkyl groups providing steric hindrance. This makes formaldehyde a better electrophile and more prone to reacting with nucleophiles compared to acetaldehyde. Additionally, the lack of alkyl groups in formaldehyde results in a greater stabilization of the transition state during reactions.
Why better is better then best?
Because better is better then best.
What is the noun for better?
The noun for better is better.
When was Better Do Better created?
Better Do Better was created on 2006-02-27.
Do alkenes react with sulphuric acid?
Alkenes react with concentrated sulphuric acid in the cold to produce alkyl hydrogensulphates. Ethene reacts to give ethyl hydrogensulphate. CH2=CH2 + H2SO4 --> CH3CH2OSO2OH The structure of the product molecule is sometimes written as CH3CH2HSO4, but the version in the equation is better because it shows how all the atoms are linked up. You may also find it written as CH3CH2OSO3H.
Who is better d-backs or Yankees?
Yankees. Better team, better league, better division, better record.
What is the better assault rifle?
Well, in order to answer that, you have to tell us what better means. Better accuracy, better power, better reliability, better firepower, better versatility, better ease of maintenance/ use, etc etc. Bottom line- there is no one single better.
What is a better word than better?
Even better!
