Who discovered carbon tetrachloride?

Answer 1

Carbon monoxide was first prepared by the French chemist de Lassone in 1776 by heating zinc oxide with coke. He mistakenly concluded that the gaseous product was hydrogen as it burned with a blue flame. The gas was identified as a compound containing carbon and oxygen by the English chemist William Cumberland Cruikshank in the year 1800. In other words Lassone discovered it and didn't know what it was. Cruikshank told him.

Answer 2

Credit for the discovery of carbon dioxide goes to Flemish scientist Jan Baptista van Helmont (c. 1580-1644; some sources give death date as 1635). Around 1630, van Helmont identified a gas given off by burning wood and gave it the name gas sylvestre ("wood gas"). Today we know that gas is carbon dioxide. Van Helmont's discovery was important not only because he first recognized carbon dioxide but also because he first understood that air is a combination of gases, not a single gas.

Some of the most complete studies of carbon dioxide were conducted by Scottish chemist Joseph Black (1728-1799). In 1756, Black proved that carbon dioxide (which was then called "fixed air") occurred in the atmosphere and that it could form other compounds. He also identified carbon dioxide in the breath exhaled by humans.
Joseph Black, a Scottish chemist and physician, first identified carbon dioxide in the 1750s.

Answer 3

it was just made by different compositions from carbon disulfide and sulfur
