Post by: helper on October 29, 2013, 04:31:57 PM

hello,
my question is attached. please give me an advise.

thank you

my it be because the higher carbonyl group is aldehyde and the other is Kenton and as I know aldehyde more reactive than Keaton because the partial charge on the C in aldehyde is more positive and therefore it tendecy to nucleophilic attack is higher?

It seems to be right for me.
Aldehydes are more reactive than ketones in nucleophilic addition for two reasons... One is steric effect, and the other one is that alkyl groups attached to carbonyl make that carbon less electrophilic.
