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.
Answer:
C) non renewable resources
Explanation:
These are resources such as oil that are formed over a long period of time but are consumed very quickly.
Answer:
The Battery Casing
Battery casing is manufactured in layers. The casing layers are developed from various raw materials and can include one or two, for example, polyethylene terephthalate layers, a polymer layer, and a polypropylene layer.
