Aldehydes are less sterically hindered than ketones. Also, aldehydes have fewer electron donating groups (EDG's) which can stabilize an electron-poor area. The extra carbon chain that ketones have that aldehydes do not have are the reason for both of these things. The neighboring carbon to the carbonyl carbon is an EDG and the carbon chain causes steric hindrance.

What is the difference in acidity between aldehydes and ketones?
Aldehydes are generally more acidic than ketones due to the presence of a hydrogen atom attached to the carbonyl group in aldehydes, which can be easily donated as a proton. This makes aldehydes more reactive towards nucleophiles compared to ketones.
Aldehydes generally undergo nucleophilic addition more readily than ketones Explain?
aldehydes have at least one hydrogen bond in their structure,hence they do not cause much hindrances to attacking nucleophiles.ketones on the other hand have at least 2 methyl groups attached to their structure hence,the methyl group cause steric strains hence makes it difficult for the attacking nucleophile to bond with the carbonyl carbon.in this case aldehydes wiil be able to react with nuclephiles faster than ketones.
How do aldehyde's and ketones differ from alcohol?
Both aldehydes and ketones contain a C=O (carbon double bond oxygen). Ketones have this C=O somewhere in their carbon chain, but not at the start or end of the chain (ie: there are more carbons attached to the carbon containing the double bond oxygen, and no hydrogens bonded to that carbon). Aldehydes have there C=O at the end, or start of the chain, and to maintain the octet rule, there is hydrogen bonded to the oxygen containing carbon (please note that it is a C=O). The functional group of alcohol is OH. This OH is bonded directly to the last (or first) carbon in the chain. The big difference is that the carbon bond oxygen is a single bond and the hydrogen is bonded to the oxygen (not the carbon, as the case of aldehydes).
Why do aldehydes and ketones add one equivalent of grignard reagent but esters add two equivalents?
With an ester, excess Grignard is needed, because the first equivalent pushes out the leaving group, and the second equivalent educes the resulting ketone into an alcohol (after protonation by water).
Is nucleophile rich or poor in electrons?
A nucleophile is rich in electrons. It is a species that donates an electron pair to form a chemical bond in a reaction, typically containing lone pairs or pi bonds. Nucleophiles are often negatively charged or neutral molecules with high electron density, making them reactive towards electrophiles, which are electron-poor species.
Why are ketones more reactive towards nucleophiles than esters?
Ketones have a more electrophilic carbonyl carbon compared to esters because they lack the electron-donating groups present in esters. This makes ketones more susceptible to nucleophilic attack. Additionally, the steric hindrance around the carbonyl carbon in esters can reduce the reactivity towards nucleophiles compared to ketones.
Why halobenzenes are less reactive towards nucleophilic substitution reaction?
i think the question is wrong.benzene doesn't respond nucleophilic substitution respond electrophilic substitution it is electrophilic then due to resonance there is a partial double bond between carbon of benzene and halogens.so halobenzenes are chemically inert towards electrophilic substitution.
What is the group that distinguishes aldehydes from most other classes of compounds?
The functional group that distinguishes aldehydes from most other classes of compounds is the carbonyl group (-C=O) with a hydrogen atom bonded to the carbonyl carbon. This unique structure gives aldehydes distinct chemical properties, such as their characteristic reactivity towards oxidation and reduction reactions.
What has the author M Norret written?
M. Norret has written: 'Synthetic approaches towards enantiopure axially-symmetric cyclic ketones and related compounds'
What metals Aluminum Copper Iron Magnesium Manganese or Zinc should be the most reactive towards oxygen?
Magnesium is the most reactive towards oxygen among the metals listed. When exposed to oxygen, magnesium will quickly form a layer of magnesium oxide on its surface, which gives it a dull appearance.
What react with potassium?
all of the halogens: bromine, fluorine, oxygen, chlorine and iodine. and it is highly reactive with water.
Is xenon more reactive than iodine?
No, xenon is less reactive than iodine. Xenon is a noble gas and is known for its inert and stable nature, while iodine is a halogen and is more reactive, especially towards other elements.
