Using molecular orbital theory, the bond order of the C-C bond in the C2 molecule is _____. g

In-s [12.5K]

Answer:

The bond order for C2 molecule is 2.

Explanation:

Bond order can be defined as the half of the difference between the number of electrons in the bonding orbital and the number of electrons in the antibonding orbitals. It can be represented mathematically by; .

Bond order,n= [number of electrons in the bonding molecular orbitals(BMO) - the number or electrons in the anti-bonding molecular orbitals(AMO) ] / 2.

The electronic configuration of the C2 molecule is given below;

C2 = (1sσ)^2 (1s^*σ)^2 (2sσ)^2 (2s^*σ)^2 (2pπ)^4.

The ones with the (*) are known as the Anti-bonding molecular orbitals while the ones without (*) are known as the bonding molecular orbitals. Hence, we have 8 Electrons from the bonding molecular orbitals and 4 Electrons from the anti-bonding molecular orbitals.

So, from the formula given above, the bond order of C2 molecule is;

===> 8-4/2= 4/2.

===> 2.

A student has a solution of sodium nitrate and believes it is saturated. Which statement provides the best evidence that the sol

dmitriy555 [2]

Answer : The correct option is, D

Explanation :

Saturated solution : It is a chemical solution which contain the maximum amount of solute dissolved in the solvent. In saturated solution, the additional amount of solute will not dissolve in the solvent.

When a student has a solution of sodium nitrate then we can check their saturation point by adding additional amount of sodium nitrate. When we add more amount of sodium nitrate in the solution, then all of it will settle down to the bottom of the container.

Therefore, the best evidence for saturated solution is, When additional sodium nitrate is added, it all settles to the bottom of the container.

Draw the structure corresponding to the followingname:_________.

natita [175]

Answer:

See figures 1 and 2

Explanation:

For this question, we can analyze each compound:

a. (4Z,3S)-2,4,7-trimethyl-3-amino-4-octene

In this case, we have to start with a carbon chain of 8 carbons. Then in carbons 2, 4 and, 7, we have to put three methyl groups ( $CH_3$ ). In carbon 4 we have to put an amino group ( $NH_2$ ). When we put the amino group in carbon 4 we will have a chiral carbon. So, we have to indicate the orientation in the bond of the amino group. If we want an "S" configuration the atoms must have a counterclockwise orientation. So, the amino group must have a dashed bond. Finally, in carbon 4 we have to put a double bond, the configuration of this double bond is "Z". So, the most important groups must be on the same side, in this case.

See figure 1 for further explanations

b. (3S,6R)-6-(2,4-dinitrophenyl)-3-amino-1-heptyne

In this case, we have to start with a chain of 7 carbons. In carbon 3 we have to put an amino group ( $NH_2$ ). When we put this group in carbons we will have a chiral carbon is the name we have an "S" configuration for this carbon. So, we have to use the dashed bond in order to have a counterclockwise orientation for all the atoms bonded on carbon 3. In carbon 6 we have to put a big group "2,4-dinitrophenyl". In this group, we have a bond with the main carbon chain in carbon 6 (of benzene), in this same benzene ring we have to put nitro groups ( $NH_2$ ) in carbons 2 and 4. Additionally, carbon 6 is a chiral carbon, and the configuration of this carbon is "R". Therefore we have to use a wedge bond for all the "2,4-dinitrophenyl" in order to have a clockwise orientation for all the atoms bonded on carbon 6. Finally, we have to put a triple bond between carbons 2 and 3.
