A 17.5% diethyl zinc hexane solution means that there is 17.5 grams of diethyl zinc dissolved in 100 milliliters (or grams) of hexane. This solution is commonly used as a reagent in organic synthesis reactions.
Diethylzinc content refers to the concentration or amount of diethylzinc present in a particular substance or solution. In this case, the diethylzinc content is stated to be 17.5%, which means that 17.5% of the substance or solution is composed of diethylzinc. n-hexane content 82.5%.
N-hexane is a hydrocarbon with the chemical formula C6H14. It is an alkane and is commonly used as a solvent in laboratories and industries. It is a colorless liquid at room temperature and has a relatively low boiling point of 69°C. N-hexane is highly flammable and can form explosive vapor-air mixtures. It is mainly derived from crude oil and natural gas.
