00:01
So we have given the name of compounds.
00:04
The first one is 4 chloro 2 phenyl pentanyl.
00:30
So now we have this pentanol here.
00:37
Okay, penit is the prefix used when we have five carbon atoms.
00:41
So we have five carbon atoms.
00:43
1, 2, 3, 4, 5.
00:49
And then it says that we have all suffix.
00:56
So all suffix is for aldehyde.
00:59
Okay, when we have ldehyde group, ldehyde functional group, that is cho.
01:05
Okay, so this is the representation for ldhyde group.
01:08
And of course, the ldhyde group must be given the least priority and the ldhru.
01:16
Is the terminal group here.
01:18
So that's why i am attaching this aldehyde group to the terminal carbon.
01:23
And now it says two phenyl.
01:26
Okay.
01:27
So if this is the first carbon, then second carbon is this, third carbon is this, fourth carbon and this, and fifth carbon is this.
01:37
So now what we have given is two phenyl.
01:41
That is on second position we have a phenyl group.
01:44
Now what do we mean by phenyl group? finile is actually the substituted benzene ring.
01:51
When you have this benzene ring and this benzene ring is substituted by any alkyl chain, by any another carbon chain, okay, another kind of group.
02:04
So we consider this as phenyl group.
02:06
Okay.
02:08
So we have the phenyl group on second position.
02:16
And then we have on fourth position a chloro group so this is the chloro group here now complete the valencies of rest of the carbon atoms with the help of hydrogen atom keeping in mind that carbon is tetravalent in nature that is it can make four bonds at one time so it requires three hydrogen atom it requires one hydrogen atom then it requires two hydrogen atom it requires one hydrogen atom and for the terminal carbon the valency is already completed so this is the structure we have okay and always remember that whenever this benzene ring is being attest to any long carbon chain then it is called as phenyl group and it is given the it is treated as the secondary group okay it is given the lower priority then we have next part which says 2 ethyl 4 propyl cyclohexanol okay so in this case this haggs the prefix and we have 6 carbon atoms cyclu represents that these 6 carbon atoms are arranged in a cyclic manner so this here is a cyclic ring containing six carbon atom okay and we have the suffix own okay suffix own represents ketone so that is we have a carbonyl carbon okay so here we have a ketonic group so this ring is called the cyclohexonon ring okay now it says four profile okay so that means if this carbon atom containing the carbonyl group so it has first position then it is third it is fourth first second third fourth fifth and six okay now it says four propile that means on fourth position we have a profile group so prop means we have three carbon atoms and is representing the alkile group so i have an alkali group which consisting three carbon atoms so, ch2, ch2, ch3.
05:22
This is the profile group here...
