Estimate the bond energy of a bond of
length 100 pm.

We are given the following diagram. And this isn't perfect but it's pretty close. And this is the potential energy of two chlorine atoms as a function of the distance between them. So as the distance increases, this is what happens to our energy. There are five parts to this. So I'm going to answer each of these parts separately. Let's start with part A Hey Says, What does an energy of 0? And energy of zero corresponds to what? And an energy of zero corresponds to two chlorine atoms that aren't interacting. That one was pretty simple. Now let's do be be says according to balance bond model, what why does the energy decrease as the chlorine atoms move from high or large separation and near one another? Yeah, I'll go nearer to one another. So as they move this way, when they're over, where I'm marking now and they're moving down here, they get to the point where the over the valence electrons can overlap. The valence electrons slash and I'll be more specific, the orbital's get close enough to overlap and then I'll say to share slash over at lap. So the electrons in the overlap orbital's our shared between the two nuclei. Okay, let's see how long she is. See asked what is the significance at the minimum point significance in the plot? And of course that would be the bond length, which is the lowest energy. Um So that represents bond length. Okay, let's move on to d We might have to bump back and forth here. Why does the energy rise after the minimum point as the chlorine chlorine get even closer and let me go back. That would mean why is this rising right here as it's moving that way? That'll be because of nuclear repulsion. The nuclei which are positively charged, where we pulse each other and last but not least. E how do you estimate the bond strength from the plot? I'm going to go back again, and when we get here again, we get down here, The lower this energy is the stronger the bomb strength, mhm, minimum energy, the stronger the bond. So the bond strength will be greatest right there. I think. That's it.

For this question, we're drawing a potential energy diagram of a cl to bond when to chlorine atoms bind together to form a chlorine molecule, the potential energy diagram shows the um but the energy associated with the bond relative to the distance between the two atoms. So when we start at great distances where the atoms are too far apart to really form a bond, we have an energy approaching zero. So we can start by drawing a diagram at high distance with energy approaching zero. And then as we get closer together, the energy will begin to decrease as the bond is forming until it reaches a minimum. And at that minimum is where we have the associated bond length of the cl to bond. As we continue to move to smaller and smaller distances, the energy will quickly increase as now the atoms when they get too close, begin to repel each other rather than form a bond. So here's a general potential energy diagram of a seal to bond. We note that the bond distance of 194 Pekka meters occurs right at the minimum point of this potential energy diagram. Additionally, the dissociation energy can be found by measuring the difference between the energy minimum and the energy of dissociation where the bond no longer exists. So when we measure this difference in energy, we can calculate it to be 240 killed joules per mole.

Hi friends here it is. Given the reduced months off. I shut up one age 19 To be 19 upon 20 into mass of hydrogen molecules and force constraint. Yeah. To be 966. Newton permitted in the first part the frequency of vibration of molecules and not. Would we Born upon to root of force constant that is 966 upon reduced mass 1.6710 to the power -27 into 20 x nine kids. On solving it, it will be 1.24 10 to the power. 20 words right to be part. Energy is given by half edge cross route of Gave up one M Nus So 4.1110 to the power of minor strategic. And the graph will be Yeah. Yeah. Mhm. That's all. Thanks for watching it.

Hello question is the bound energy in kilocalories per mole of carbon. Single bond carbon is approximately. So we are going to discuss, what is the bound energy of a single bondage? Approximately born energies define its energy required to break the bond of the molecule, or single. So carbon single one carbon is that has the least number of bones. If carbon single one carbon has the least number of bones then born energy and be also at least yes or no. So in the kilocalories per mole carbon, single bone carbon has 100 kg calorie caramel. That is the bond the energy of the carbon carbon carbon. Right so correct the C. C. Is the correct option. Okay, thank you. Oh.
