Hello everyone let's look at the question.
00:06
So here we are asked to classify the given monoseucaride so depending on their position of carbonyl group and the number of carbon atoms it contains.
00:19
So the first molecule is so first let us write the first molecule c h -2 -oh -h c double bond o h -oh c -h c -h 2 -oh okay now, so in this case, see here there are many options are given.
00:45
Okay.
00:46
Now, so while naming the carbohydrates, so first we have to find out how many carbon atoms are present.
00:55
So here one, two, three.
00:57
So three carbon atoms are present.
00:59
So that's why.
01:00
So here we will use try as the prefix.
01:05
Okay so here and another thing is so before that we should find out the the functional group present in the molecule so here say if you take the carbohydrates lots of hydroxyl group will be there alcohol a group will be there okay so that's why we cannot name or include all the hydroxyl group because it will it will become lengthy that's why so since it contains either aldehyde group or keto group we will mention that groups okay so here so here it is a keto group that's why so the first comes the functional group name that is keto okay then comes the number of the carbon atoms it is try okay and carbohydrates the suffix is o s e so it is quito trios okay so this is the the name of this the general the name of this what the first compound okay the first monosacry or the carbohydrate.
02:13
Let us consider the second one.
02:15
So here the second one is the harvard structure.
02:22
So here it is oh, th to oh, th to oh and then oh h, oh h, oh h, and here it is ch to oh and then h.
02:44
Okay now so this is the harvard structure of a carbohydrate so it is how it's structure okay so this is form a by intramolecular reaction in case of carbohydrates.
03:07
Okay, now, so first we should know how this harvard structure is found...
