What makes C=O more stable that C(OH)₂

When there are $2$ hydroxy groups on same carbon, they tend to undergo dehydration ( of course with exceptions like chloral where $\ce H$ bonding prevails). Why does this happen? We are breaking a ...

Is magnesium sulfate basic, neutral or acidic?

A question in my college test was whether $\ce{MgSO4}$ is neutral, acidic or basic. I was told to solve this kind of problem by hydrolyzing any ions that do not "come from" a strong acid or a strong ...

Why can NCl3 be hydrolyzed but CCl4 cannot?

While explaining why $\ce{CCl4}$ cannot be hydrolyzed, we say carbon atom doesn't have any d-orbitals and therefore a water molecule (lone pair electrons of $\ce{O}$ atom) cannot form coordinate bond ...

Why are silyl chlorides more readily hydrolysed than alkyl chlorides?

I know that the $\ce{Si-Cl}$ bond has a slightly higher energy, but silyl chlorides are much more readily hydrolyzed compared to alkyl chlorides. I do not fully understand why that is. My thoughts so ...

Hydrolysis of salt

The hydrolysis of salt tells you whether a salt is acidic or basic. But it does not tell you how acidic or basic a salt is. Is there a way to determine this? My guess is that taking of the weak base ...

How is it possible, that the hydrolysis of ethers proceed via a SN2 mechanism?

Ethers on hydrolysis with dilute $\ce{H2SO4}$ under pressure produce alcohols. This is basically a type of acidic cleavage of ethers by the SN2 mechanism. (source) There is inversion of ...

Why doesn't an acid-base reaction occur in basic amide hydrolysis instead of nucleophilic acyl substitution?

In the reaction of Grignard reagent with a primary and secondary amide, nucleophilic acyl substiution doesn't happen. The reason given is that R- is a strong base as well as strong nucleophile, an ...
