  1. 5 days ago · The atomic number of carbon is 6, which means its atom has six electrons outside of the nucleus. So, the first two electrons enter the 1s subshell, the next two electrons enter the 2s subshell and the remaining two electrons enter the 2p subshell. Therefore, the electron configuration of carbon is 1s2 2s2 2p2.

  5. 3 days ago · Heteroaromatic molecules are found in areas ranging from biochemistry to photovoltaics. We analyze the n,π* excited states of 6π-electron heteroaromatics with in-plane lone pairs (nσ, herein n) and use qualitative theory and quantum chemical computations, starting at Mandado’s 2n + 1 rule for aromaticity of separate spins. After excitation of an electron from n to π*, a (4n + 2)π ...

  6. 3 days ago · 1 Using different types of models to represent carbon compounds. When students learn to use electron dot structures to represent carbon compounds, these diagrams relate a molecular formula such as CH 4 or C 2 H 6 to the number of covalent bonds available as a consequence of the number of valence electrons for each kind of atom.

  7. 5 days ago · The blue numbers put the leftmost hydroxy group at the third main-chain carbon atom (3) and the rightmost hydroxy group at the second main-chain carbon atom (2). The red and blue numbers both indicate that the infix should be -2,3- and that the molecule should therefore include the butane-2,3-diol term.

  8. 5 days ago · The high value (in absolute value) of the interaction energy (-135.25 Kcal/mol) and the value of the lowest probability energy distribution P(E) (0.429) is attributed to the complex in basic medium, which indicates that the AC/TBBPA system is stable in a basic medium and that the adsorption of TBBPA molecules on AC is kinetically unstable ...
