Hello students i come here in this question we have some compounds so they are given newman projections like this so we had to write the line structure and iupac name for these compounds so if you see here this is a front carbon which is present so for friend carbon we can write it is ch 3 and this one is attached to another carbon so here it is first carbon and second carbon is this one so which is having ch2 c h is there and h is there so this is the structure of the compound so what is the structure this one is one two three four carbons are present so it is is a butane compound is butane.
01:15
Okay nothing but butin is the compound and the second structure here b is you see here this is ch2 ch3 and this one is ch3 this one is ch3 here it is ch3 here it is so here this one is the front carbon which is having one h is there and one ch3 is present here.
01:58
So ch2, ch3, ch2, ch2, right here, ch3 here it is present.
02:15
And this carbon is having one ch3, one h.
02:19
H and here it is a bag carbon having 2 ch3 which 3 here and another c .h.
02:30
H is present.
02:31
So this is a carbon.
02:33
So 1, 2, 3, 4.
02:38
But we want a least number of carbon.
02:41
So 1, 3, 4, 5 carbons.
02:45
So 5 are present.
02:47
So here if you see this one is having second and third is thymethyl, 2 comma 3 dimethyl pendant is the compound.
03:02
Now the third structure, so if you see the structure of the third one is right here, so here it is given like this h, h and br and this one is ch3, ch2, ch3, and this one is this one is h itself, i am not the case of c .h.
03:40
Okay, so if you see the structure of this one, so c, v, r, h, h, and c, c, h, and c, h, and c, h.
04:00
So this one is two methane, one, so first carbon, second carbon, third, fourth one bromine two methyl butane is the compound now the third structure fourth structure it is here it is ch3 and this one is having sorry i'm given like this clh ch3 ch3 ch2 ch3 here it is c h c h c h c h c h c h c h c h 3 here it is c h c h here it is h and here it is c h, c h, c h, c h, c h twice.
05:10
So you like the line structure here.
05:13
So if you see the first carbon, c, c, h, c, c h 3, and for this one there is another ch is present.
05:24
And there is a carbon here, so this for this carbon, h is there and here it is cl and the second carbon.
05:33
There is a c, ah h is present and here it is a c h, c h 3, c h 3, sorry c h 2, ch 3, back carbon.
05:51
One is having ch 3 and another is ch2, ch3.
06:04
Okay, this one is c2, ch3.
06:06
This one is ch, this one is ch3.
06:11
So this one is having one ch3 and one h and ch2 says three okay so how many carbons are present? one, two so three four five six seven carbons so one two so one two three five six this one is and seven carbons are present sorry one it is two three four four four 5, 6, 1, 2, 3, 4, 5, 6...
