Electrophilic Reactivity of Tetrabromorhodamine 123is Bromine Induced: Convergent Interpretation through ComplementaryMolecular Descriptors.Nucleophilicaddition of water and of methanol to 3,6-diamino-2,4,5,7-tetrabromo-9-[2-(methoxycarbonyl)phenyl]-9H-xanthen-9-ylium, 4BrR123, yields respectively2-(...
F2. This is typically described in high-school chemistry as a simple example of covalent electron-sharing, but the purely covalent contribution to the bond turns out to be repulsive. The atoms can instead be considered to be held together ...
Figure 1 the molecular formula of p-Anisaldehyde Usually it is white or light yellow solid, low solubility in water, soluble in organic solvents such as ethanol and acetone, active bromine content is about 54%, stable in dry state, easy to absorb moisture, partially hydrolyzed after moisture a...
Extrusion of this polymer showed almost equal leaving of the Cl and Br species, unlike the case of thermal activation, which shows almost exclusively bromine migration. Following the confirmation of bond scission and ring opening under shear in these systems, the possibility to form bonds in ...
Given that the molecular mass of a compound is 360 g/mol, and that it has an empirical formula of CH2O, what is its' molecular formula? What is the formula for carbon bromine? What is the general formula for alkanes? What is the condensed structural formula of 2-Methylbutane?
Show two different methods of making 4-methyl-3-hexanone starting from 3-pentanone. The methods cannot differ by something trivial such as using chlorine instead of bromine. How can you distinguish the following compounds using spectroscopic method...

Is dinitrogen Tetrahydride polar or nonpolar? It's polar. If we're thinking of the same structure (Br)2-N-N-(Br)2, then the bromines lower the electron density of the nitrogen atoms, creating a dipole moment. Does N2 contain polar bonds?
was added bromine (0.32 ml, 6.2 mmol, 1.02 equ) in chloroform (5 ml) over 20 minutes. The reaction was stirred at −12° C. for 50 minutes, then poured into water (20 ml). The organic layer was washed with water (10 ml), 10% sodium thiosulfate (2×10 ml), and water (10 ...
A solution of bromine in acetic acid (0.6M; 7.2 mL; 4.32 mmol) was added to a stirred suspension of 5-(2,4-Bis-benzyloxy-5-chlorophenyl)-4-bromo-isoxazole-3-carboxylic acid ethylamide (2.00 g; 4.32 mmol) and sodium acetate (0.708 g, 8.64 mmol) in acetic acid (30 ml) at ambient...
