* The Lewis dot structure for H2molecule is shown below. Note that each hydrogen gets two electrons after forming the bond. The bond between two hydrogen atoms can be shown as a line, which represents a bond pair of electrons. Note: The bond between two hydrogen atoms is non polar since...

A correct Lewis structure will follow the octet rule, meaning that each atom (except hydrogen) has a full outer shell of 8 electrons. In addition, the formal charges of each atom should be minimized and the overall charge of the molecule should be neutral. ...
A hydrogen-free variation of the Pinner reaction is presented, in which alcohols react with carbonitriles to furnish the corresponding carboxylates under mild conditions.doi:10.1002/chin.201310095Pfaff, DominikNemecek, GregorPodlech, JoachimChemInform...
`冷冻保存方法一:冷冻管置于4℃300分钟→(-20℃30分钟*)→-80℃16~18小时(或隔夜)→液氮槽长期储存。 冷冻保存方法二:冷冻管置于已设定程序之可程序降温机中每分钟降1-3℃至–80℃以下,再放入液氮槽期储存。-20℃不可超过1小时,以防止冰晶过大,造成细胞大量死亡,也可跳过此步骤直接放入-80℃冰箱中,但存活...
there are some unusual examples of very stable carbocations that take the form of organic salts. Crystal violet is the common name for the chloride salt of the carbocation whose structure is shown below. Notice the structural possibilities for extensive resonance delocalization of the positive charge...
structure gav C-type immune lectins (CLRs): Dendritic cell-specific intracellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN), its closely related protein DC-SIGNR and the Langerhans cell CLR Langerin were chosen for the microarray study. Whilst DC-SIGN is known to bind both to mannose-...
Explain why oxalic acid is stronger than Malonic acid for the first deprotonation. Explain how to make 2 L of 0.17 N HCl. Describe the behavior of chloride towards concentrated H_2SO_4. Define amphoteric behavior and give an example of it. Is Ozone (O3) an acceptable Lewis structure? Why...
Step 3: Analyze the structure of BCl3Boron trichloride (BCl3) has an incomplete octet and possesses vacant orbitals. This allows it to accept electron pairs, making it a Lewis acid. Step 4: Analyze the structure of PH3Phosphine (PH3) has a lone pair of electrons on the phosphorus atom...
(entry 4). Yet, when using the weaker Lewis acid AlEt2Cl, alkenyl chlorides3formed exclusively, i.e., the desired3awas obtained in 92% yield and the formation of side products was not observed (entry 5; for more details, see also Supplementary Fig.76in SI). AlEt2Cl has already been...
