LDA is a base, and a strong one at that with a pKa of approximately 25 It is typically used for removing hydrogen atoms for aldol reactions since this makes the reaction irreversible and prevents various side reactions occuring.
LDA has 2 isopropyl groups attached to a central nitrogen atom which yields a negative charge making the compound basic.
In the deprotonation of cyclohexanol, LDA (lithium diisopropylamide) acts as a strong base to remove a proton from the hydroxyl group of cyclohexanol, forming cyclohexoxide. This reaction is important in organic synthesis to create new compounds.
LDA, or lithium diisopropylamide, is a strong base commonly used in organic chemistry reactions to deprotonate acidic hydrogen atoms. It is often used in reactions where selective deprotonation is necessary for synthesizing specific molecules. LDA is particularly effective at generating carbanions, which are key intermediates in many organic reactions.
n-BuLi is stronger. This is derived from understanding whether carbon or nitrogen is more electronegative. Carbon is LESS electronegative than nitrogen, which means it's better at donating electrons and not accepting electrons (remember the trend of decreasing electronegativity "FONClBISCH"). A Lewis base that is better at donating electrons is defined as the stronger base.
The strongest base known in chemistry is lithium diisopropylamide (LDA). It is highly reactive and strong compared to other bases, meaning it can easily donate electrons and react with other substances. LDA is often used in organic chemistry reactions due to its powerful basic properties.
Examples of sterically hindered strong bases include tert-butoxide (t-BuO-) and LDA (lithium diisopropylamide). These bases are bulky, preventing close approach to the acidic proton, enhancing their basicity and allowing them to perform selective deprotonation in organic synthesis.

In the 8085, the LDA instruction loads the accumulator from memory, while the STA instructionstores the accumulator to memory. LDA is a read, while STA is a write. LDA is opcode 3AH, while STA is opcode 32H.

LDA in terms of computer system architecture stands for Logical Device Address. A LDA is a one byte address (i.e an upper MAC address) and there is no physical address (i.e lower MAC address) specified.
