R-CHOH-CH3 + I2, NaOH 會變咩-－zogfly3的部落格

標題:

R-CHOH-CH3 + I2, NaOH 會變咩?

發問:

R-CHOH-CH3 + I2 , NaOH 會變 [R-COO]- or [R-CHOHO]- ? triiodomethane test

最佳解答:

If you test for the presence of -COCH3 in a organic compound by adding I2(aq) followed by NaOH(aq), the test is called triiodomethane test or iodoform test. If you convert the compound RCOCH3- to RCOO- by adding I2(aq) followed by NaOH(aq), the reaction is called triiodomethane reaction or iodoform reaction. The equation is : RCOCH3 + I2 + Na+OH- → RCOO-Na+ + CHI3 2007-03-17 01:20:23 補充： Reference :http://www.answers.com/topic/iodoform-reaction 2007-03-17 01:21:56 補充： There is NO such compound R-CHOH(-)(Na ) as in the first replier's answer. 2007-03-17 01:27:01 補充： This is because it will exist as RCH2O(-)Na( ) instead, which is NOT the product of triiodomethane reaction.
