Show how $HC\equiv CH, CH_3CH_2Br, and (CH_3)_2CHCH_2CH_2Br$ can be used to prepare
$CH_3CH_2C\equiv
CCH_2CH_2CH(CH_3)_2$. Show all reagents, and use curved arrows to show
movement of electron pairs.

Hello and welcome to this video solution of numerous. So here you have to calculate the number of electrons presently. 9.5 9.5 g of e 04 And it's three. Right? So first we'll calculate the total number of moles number of moles. Yeah, of pure for three miners. Okay, in 9.5 g is equal to the total mass 9.5 g by the molecular mass of Pure. For right. So this is equal to 0.1 Molds right now. The number of electrons in one iron which will have so a number of electron force for us is its atomic mass atomic number. Sorry. So if you have for for phosphorus cities 15 great 15 and for oxygen we have got eight. So total number of electrons. uh, so any let's say is equal to 15 plus four times of eight. Right? There are four oxygen Plus three rate due to discharge negative charge. So if you see it is 50 right now. Thus we can say the total number of electrons guarantees total electrons to transcend and .5 g Is equal to 15 times of 0.1 moles. Right, So is he going to fight Moles? Which is equal to five times the I have a greater number. So we have options, see as the correct one. I hope it is clear to you and have a very good rest of the day. Thanks.

Here we will write the electron door formula for the given molecule in party. Okay. S E O C L two. And here total violence electrons are 26. So yeah, selenium is the central element and oxygen. Yeah. Memory and chlorine. Yeah. And next is part B. Uh yeah C S E two. Total 16 valence electrons. And if an electron door formula is carbon is the central element makes to make double one with selenium. Thank you. Selena. And boxy me here see a CN four negative and total. Yeah, weddings electrons are 22. So yeah, the electron door formula is C A. See a negative. And yeah, negative charge will disperse on the whole molecule. My next party is C two. Do want to get you total valence electrons are okay. Yeah. So this uh carbon make triple bone, triple bones with the cover and the negative charge were dispersed for the whole molecule to negative. And these are the electron door formula for the U. N. Was killed in the costume.

Hello. Question is we have to question is launching magical column. So we have to do correct column match First. Is that except for XC four have to longer of electron. That is why I believe that is choir planner I C F or have a long pair of electrons. That's why it will be the preliminary XC or three. Do not have a longer of leftover. That's why it will also sunny sc effort is the sea so and exceed. What is the criminal and X E Or 3? Is that correct? And is the correct colour match? Because geometry is dependent on the number of long pair Axiom four have too long pair of electron that psychic to Squire being mhm In the SCFO in the SCF would have to one number of electron. Yeah. Mhm. Mhm. Yeah. Okay. Okay. Mhm. Mhm.

Here. We are continuing on with our coordination chemistry and populating non degenerate orbital's. So in the first example here we have our rope tools and we have four unpowered electrons because we have a default high spin, We have 123 four where we have CR two plus that has three deep Orbital. Is the violence orbital with four electrons in it. Next what we have is following. So we draw the same set orbital's got D five high spins. We have 12345 electrons, 51 pad electrons Where the MN two plus balance did orbital is three D 5. Following on from this, we draw the same set of orbital's and we've got D six low spin to have 123, 4-56. So we've chosen to power of our electrons rather than putting our electrons in a higher energy orbital. Because this gap energy gap here in between the two sets of orbital's is too great. Where are you two plus has a 46 configuration. Next. What we have is IR four plus, which has the valence configuration for 14 5 D five. We've got D five low spin. So we have 12345.1 impaired electron there. Next we have is cr three plus, which is three D 3. So whether it's high speed or low spin, it doesn't make a difference. We've got three electrons in the bottom outside of orbital's. Next we have three D 8, 1234567 and eight. And again, whether it's high or low spent doesn't make a difference. And I two plus with a three D 8 violence electrons. What we've got is to and pound electrons in the higher energy side of orbital's.
