Let us try to name this compound. Okay? Now the longest chain is this. One, two, three, four, five, six, seven, eight, nine, ten. One, two, three, four, five, six, and seven. So better to name. Name it from left to right. Just look at two, three, four, five, six, seven, eight, nine, ten. Okay? Now one thing that I would like to emphasize, when things are written like these, they are dangerous. When written like this. Okay? So you should first convert into the full structure. So see, fourth. Now see has an edge connected here. Okay? So these two have no other way than to be connected like this. So CH3, CH, CH2, CH3, okay? And, and it is C, C, C, C, C. Okay. Now this is, this is named four. This is five. And this is one, two, three, four. Maybe, maybe I could have written it here. Seven, eight, nine, ten. So it is basically a decaying, decaying, okay? It's a decaying and I have, at four I have what? Izo propyl, so Izo propyl and I will be considered for alphabetical writing. And at five I have sec-butyl. This is a sec-butyl, is it not? Sec-butyl here this will be considered. So B comes before I and I then integrate them together. So it will be five sec-butyl, okay? Then four Izo propyl and then decaying, decaying, okay? Yes? To be five sec-butyl is, is it not, but it is sec-butyl. What, what, what? I didn't get you. So it is five sec-butyl. Four Izo propyl sec-butyl is written like this, okay? So this will become scavenger. Yes, I didn't get you. Four Izo propyl. Four Izo propyl. Five, one methyl propyl decaying. Five. Five. One methyl propyl decaying. One methyl. One methyl, one two three four. One two three-one methyl propyl decaying. Yes, propyl decaying. Yes, that is also okay. But normally those five which have been told to you, the Izo and the, okay? They are written like that. If they are there, then you don't write them as a side chain. Not that it is something that is wrong, but they are inculcated as, as IUPAC names. Okay? Understand? We go to the next one. So, say, okay? And here I have, putting this. Now, many a times what happens? What happens? They will write it as what? They write it as what? They might write it as C, C, CH3, O3. Let us hold that. So, C is connected to a C, which is again connected to three C's. So, that is why it is important for you to expand and write the full structure before you attempt any anything else. So, so it is one two three four five six seven eight nine one two three four five. Either way it is five. Let me do this three four five six seven eight nine. Okay? At five the numbering is like this. One? No. It is, it is, it is, yeah, it is Neo-Pantil. Neo-Pantil also. Yes. So, it is five, five Neo-Pantil, Non-N, Non-N. And this will be, this will have to be C, H, true, no? Or you can inculcate both of them. Because for this, for this five two two, Di-Metal, Propel, Propel, Non-N, that is also a value name.
