Please Help. I really dont understand ):
In which of the following can hydrogen bonding occur?
in a pure acetone (propanone)
in a mixture of acetone and formaldehyde
in a pure formaldehyde (methanal)
in none of these cases
D Question 3 1 pts Consider the following biochemical reaction. O-C-CH-CH-C-O+? O-C-CH2-CH2-C-O +? To complete the reaction, which redox coenzymes should be used to replace the question marks, respectively? O Any of the above could be used O NADP+, NADPH O NADt, NADH FAD, FADH2Explanation / Answer
Answer:- In none of these cases
A hydrogen bond is an electrostatic force between hydrogen (H) atom covalently bound to a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F) with another electronegative atom in the vicinity.
In a pure acetone (propanone) we have electronegative oxygen but no hydrogen directly attached to the electronegative element bering partial positive charge so there will be no hydrogen bonding.
Similar is the case for mixture of acetone and formaldehyde & pure formaldehyde (methanal) so there will be no hydrogen bonding.
If we put these in the water the hydrogen bonding is possible.
