Hello azmanam,
Thank you for that explanation, I understand and realize my mistake.
However I must then turn my attention to either d or e. because both b and c are FALSE.
I will first reword the questions:
d. There is a good leaving group in acyl chloride than in an aldehyde
--> An acyl chloride does have a leaving chloride ion, however when examining the mechanism of hydration of an aldehyde in a basic solution, there is not 'leaving group' other than a hydroxide ion. But unlike the acyl chloride there isn't really a leaving group.
e. The aldehyde has a readily oxidizable hydrogen and an acyl chloride does not
--> to be honest I don't even really understand what this is saying. I have wikipedia'd this and am realizing that perhaps it's trying to say that the H readily accept an O??? But this isn't the case, because generally it is the O of the aldehyde that accepts H (which is what I believe to be opposite to what the questions is saying?)
Would you be so kind to shed some further light azmanam.
I am grateful for your time.
