WebA Lindlar catalyst is a heterogeneous catalyst that consists of palladium deposited on calcium carbonate or barium sulfate which is then poisoned with various forms of lead or sulfur. It is used for the hydrogenation of alkynes to alkenes (i.e. without further reduction into alkanes) and is named after its inventor Herbert Lindlar . WebKetones (except propanone and butanone) must have a number to indicate the location of the carbonyl group. 2) Name other functional groups as usual. An older way of naming ketones was to name the groups attached to the carbonyl then add the word “ketone.” Thus, butanone was methyl ethyl ketone and 2-pentanone was methyl propyl ketone. pleasant view rampage
