Here is a question about this article: Compounds that contain a carbon-copper bond are known as organocopper compounds. They are very reactive towards oxygen to form copper(I) oxide and have many uses in chemistry. They are synthesized by treating copper(I) compounds with Grignard reagents, terminal alkynes or organolithium reagents; in particular, the last reaction described produces a Gilman reagent. These can undergo substitution with alkyl halides to form coupling products; as such, they are important in the field of organic synthesis. Copper(I) acetylide is highly shock-sensitive but is an intermediate in reactions such as the Cadiot-Chodkiewicz coupling and the Sonogashira coupling. Conjugate addition to enones and carbocupration of alkynes can also be achieved with organocopper compounds. Copper(I) forms a variety of weak complexes with alkenes and carbon monoxide, especially in the presence of amine ligands.
What is the answer to this question: What is produced when copper compounds are treated with organolithium reagents?
****
So... Gilman reagent


Here is a question about this article: Football is the most popular sport amongst Somalis. Important competitions are the Somalia League and Somalia Cup. The multi-ethnic Ocean Stars, Somalia's national team, first participated at the Olympic Games in 1972 and has sent athletes to compete in most Summer Olympic Games since then. The equally diverse Somali beach soccer team also represents the country in international beach soccer competitions. In addition, several international footballers such as Mohammed Ahamed Jama, Liban Abdi, Ayub Daud and Abdisalam Ibrahim have played in European top divisions.
What is the answer to this question: What sport do Somalis most enjoy?

So... Football


Here is a question about this article: The Desert Land Act of 1877 was passed to allow settlement of arid lands in the west and allotted 640 acres (2.6 km2) to settlers for a fee of $.25 per acre and a promise to irrigate the land. After three years, a fee of one dollar per acre would be paid and the land would be owned by the settler. This act brought mostly cattle and sheep ranchers into Montana, many of whom grazed their herds on the Montana prairie for three years, did little to irrigate the land and then abandoned it without paying the final fees. Some farmers came with the arrival of the Great Northern and Northern Pacific Railroads throughout the 1880s and 1890s, though in relatively small numbers.
What is the answer to this question: How much was the charge per acre at first?
****
So...
$.25
