Answer:
Compound x =
Explanation:
Let the compound be x
Assuming we have a 100g of compound x
<u>Given the following data;</u>
Magnesium, Mg = 21.6% = 21.6g
Carbon, C = 21.4% = 21.4g
Oxygen, O = 57.0% = 57.0g
Now, we would find the amount of moles for each element.
Atomic mass of Mg = 24.30g
Atomic mass of C = 12.01g
Atomic mass of O = 16.00g
<u>Amount of moles for Mg;</u>
21.6*(1/24.30) = 0.89mol
<u>Amount of moles for C;</u>
21.4*(1/12.01) = 1.78mol
<u>Amount of moles for O;</u>
57.0*(1/16.00) = 3.56mol
We then divide by the smallest to find the ratio;
0.89/0.89 = 1 Mol of Mg
1.78/0.89 = 2 Mol of C
3.56/0.89 = 4 Mol of O
Therefore, the ratio of Mg, C and O is 1:2:4.
Compound x =
Hence, the empirical formula of the compound is
Answer:
Lithium diisopropylamide [(CH3)2CH]2NLi.
Explanation:
Lithium diisopropylamide (commonly abbreviated LDA) is a chemical compound with the molecular formula [(CH3)2CH]2NLi. It is used as a strong base and has been widely accepted due to its good solubility in non-polar organic solvents and non-nucleophilic nature. It is a colorless solid, but is usually generated and observed only in solution. It was first prepared by Hamell and Levine in 1950 along with several other hindered lithium diorganylamides to effect the deprotonation of esters at the α position without attack of the carbonyl group.
