I'm not sure what a red rose smells like - those that I get from my florist are pretty much odorless (the odor-releasing process goes hand in hand with withering) 
When you smell a real rose, you smell dozens or hundreds of different molecules. There are two roses cultivated for perfumery, Rosa damascena and Rosa centifolia ('Rose de Mai'). Rose in perfumery consists of a handful of aromachemicals that are the main constituents of 'rosy smell' (recognizing the molecules that float around live roses is called 'headspace technology') - betadamascenone, rose oxide (also found in wine), geraniol, rhodinyl, ionones (shared with violets), phenylethanol are some of them. If you want to extract the smell of rose, there are two main methods. Steam distillation 'cooks' the rose, smelling jammy and edible. So although the process uses real roses, the outcome is not 1:1 flower-like - rather, it's like marmalade is to oranges. Solvent distillation gives you a fresher rose. The naturals are very expensive, so these days most roses on the market are made from synthetics. But because rose perfumes have a long tradition, you'll find the jammy styles too, because that's what traditional rose absolutes smell like. Depending on the proportions used, perfumers can emphasize the jammy, raisin-like qualities or the dewier, fruitier, more translucent aspects of rose.
