Number of framework electrons in carbonanes C2B5H7 is 16.
Framework Electrons in Carbonanes
Carbonanes are a class of compounds that contain carbon atoms in a framework structure. The framework electrons refer to the valence electrons of the carbon atoms that participate in bonding within the framework.
The framework electron count can be determined by counting the valence electrons of the constituent atoms and considering the type of bonding present in the compound.
Determining the Valence Electrons
To determine the number of framework electrons in carbonanes C2B5H7, we need to consider the valence electrons of carbon (C), boron (B), and hydrogen (H) atoms.
Carbon (C) has 4 valence electrons.
Boron (B) has 3 valence electrons.
Hydrogen (H) has 1 valence electron.
Calculating the Number of Framework Electrons
1. Counting Carbon (C) Atoms:
In C2B5H7, there are 2 carbon (C) atoms. Therefore, the number of valence electrons contributed by carbon is 2 * 4 = 8.
2. Counting Boron (B) Atoms:
In C2B5H7, there is 1 boron (B) atom. Therefore, the number of valence electrons contributed by boron is 1 * 3 = 3.
3. Counting Hydrogen (H) Atoms:
In C2B5H7, there are 7 hydrogen (H) atoms. Therefore, the number of valence electrons contributed by hydrogen is 7 * 1 = 7.
Total Valence Electrons:
The total number of valence electrons in C2B5H7 can be calculated by summing up the valence electrons contributed by each atom:
Total valence electrons = (Number of C atoms * Valence electrons per C atom) + (Number of B atoms * Valence electrons per B atom) + (Number of H atoms * Valence electrons per H atom)
Total valence electrons = (2 * 4) + (1 * 3) + (7 * 1)
Total valence electrons = 8 + 3 + 7
Total valence electrons = 18
Framework Electrons:
The framework electrons are the valence electrons that participate in bonding within the carbon framework. In C2B5H7, there are 18 valence electrons, but 2 electrons are involved in bonding between the carbon atoms. Therefore, the number of framework electrons is 18 - 2 = 16.
Hence, the correct answer is '16'.
