  • Acidity of aldehydes - Chemistry Stack Exchange
    Which is more acidic between methanal ($\ce{HCHO}$) and ethanal ($\ce{CH3CHO}$) Please explain using General organic chemistry basic concepts My Effort: I saw the stability of the conjugate base It would be $\ce{HCO-}$ and $\ce{CH2^{(-)}CHO}$ Due to resonance I can say that second one is more stabilized and thus a better acid
  • organic chemistry - How do I determine the average carbon oxidation . . .
    Determine the oxidation number of carbon in (A) ethanol and (B) ethanal Answers are (A) -2 and (B) -1 I reviewed similar question at SE: Oxidation of Carbons and I found first answer to be clear and links given in this answer to be useful I also found a good Khan Academy video, which basically confirms all in this answer
  • organic chemistry - what is the cross aldol product of ethanal and . . .
    $\begingroup$ The anion of ethanal may form, and may react with acetone but it can just as easily break down reforming the starting materials if that is not the most energetically favourable pathway Don't get hung up on which anion forms fastest, it is not the factor that determines the outcome $\endgroup$
  • Why hydrogen bonds are stronger than Van der Waals forces?
    In ethanal $\ce{CH3CHO}$, the $\ce{H}$ atom is bound to an atom (carbon) which has nearly the same electronegativity The electron of this $\ce{H}$ atom is not moved so strongly between the two atoms $\ce{C}$ and $\ce{H}$ So this electron protects the nucleus from approaching negative charges The H-bond in ethanal is quite weak
  • Why is ethanol not an oxidizer? - Chemistry Stack Exchange
    In ethanol, there isn't the same possibility for reduction as the molecule is already in its lowest oxidation state Even ethanal (an oxidation level up) isn't particularly oxidising (despite being able to accept electrons and become formally reduced)
  • organic chemistry - Why arent methanal and ethanal also ketones . . .
    Why aren't the aldehydes methanal formaldehyde and ethanal acetaldehyde also ketones? Ketones are defined by replacing any H - C - H in an alkane with C=O, which is true for both of these: methanal replaces two hydrogen atoms in methane with C=O, while ethanal does it with ethane
  • Is ethanol an acid or a base or amphoteric?
    Because we are talking about Brønsted–Lowry acids and bases, we are only concerned with whether or not a molecule has (or the degree to which it has) the ability to donate a proton (acid) or the ability to accept a proton (base) or to do either (amphoteric)
  • Iodoform test for ethanol? - Chemistry Stack Exchange
    Stack Exchange Network Stack Exchange network consists of 183 Q A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers
  • How does sodium in ethanol reduce carbonyl compounds?
    According to my teacher, Na in ethanol reduces carbonyl compounds (e g aldehydes and ketones) to alcohols However, I can't see where the hydrogen needed for reduction comes from How does the red
  • How to convert ethanal to 2-hydroxy-3 butenoic acid?
    Once you have got your acrolein from the aldol condensation of ethanal and formaldehyde you can react it with $\ce{NaCN, HCN}$ under kinetic control to get direct addition of the cyanide to the enone, forming a cyanohydrin [1] The nitrile can then be hydrolysed in aqueous acid to yield the carboxylic acid
