Thank you for all participants supporting this blog. Especially the download link's sources and bibliographies.

I'm not an expert teacher or lecturer of chemistry. I was only a student from SMA NEGERI 15 SURABAYA who had been one of the Bronze Medalist Participants of Olimpiade Sains Nasional X (2011) of Chemistry In Manado, North Sulawesi, 11 - 16 September 2011 and graduated in 2012. Now, I'm studying at Universitas Airlangga in Surabaya, Indonesia. I do love chemistry and I would like to help them who had difficulties in studying chemistry. That's why, please understand me if you found some misconcepts in my entries. Suggestions are always necessary in order to develop this blog. And I'm sorry because my English isn't so well.

All posts are originally created by me. I never stole from any sites or somebody's blog. Although sometimes I took pictures or data from other sites, I always wrote the source of that pictures or data.

Kondensasi Aldol

Reaksi ini memanfaatkan keasaman Hidrogen Alfa untuk pembuatan dimer kondensasi. Sebagai contoh pembuatan β-hidroksi-karbonil dari senyawa etanal.

Mekanisme reaksi:


Mekanisme reaksi diatas adalah reaksi tautomerisasi keto-enol. Terjadi reaksi kesetimbangan antara keto dan enol, tetapi kesetimbangan lebih cenderung mengarah ke arah pembentukan enol. Bentuk Enol (Alkena-Alkanol) inilah yang dapat menyerang Etanal.
