Broccolini (original Japanese: ãã­ãã³ãªã¼ã) is a green vegetable similar to broccoli but with smaller florets and longer, thin stalks. Often misidentified as young broccoli, it is a hybrid of broccoli and kai-lan, both cultivar groups of Brassica oleracea.
A 100% yield means that no product has been lost, while a 0 per cent yield means that no product has been made. There are several reasons why the percentage yield of a product might be less than 100 per cent, including loss when: 1  Filtering. 2  Evaporating. 3  Transferring liquids. 4  Not all reactants react to make product.
Up until now, all our reactions have taken place under ideal conditions. However, ideal conditions don't exist in real life. Reactants may be impure, reactions may not go to completion, or given reactions may have to compete with several smaller side reactions. In fact, in the laboratory, if you get 60% of the expected amount of product, that is considered very good. Now, let's talk terminology. The calculated or expected amount of product is called the theoretical yield. The amount of product actually produced is called the actual yield. When you divide actual yield by theoretical yield you get a decimal percentage known as the percent yield of a reaction.
