Hello everyone let's solve this question this question we have to solve we have to draw some structures the first one is the structure of sodium and chlorine atoms so let's start so atomic number is 11 and mass number is 23 for chlorine it is 17 and let us consider this isotope having mass 35 so here if we write the electronic configuration of sodium it is 281 and this is 287.
00:32
So let's draw the structure now.
00:35
In the center we have nucleus and in the nucleus there are 11 protons and because the mass number is 23 the number of neutrons will be 12 because proton plus neutron is equal to mass number.
00:49
Now this is the nucleus and around the nucleus we have the shells.
00:56
So let's draw them.
00:57
This is the first one.
00:59
We will draw three shells as it is 281 this is n equals to 2 that is second shell and this is n equals to 3 that is third shell so here in the first shell we have two electrons we are representing electrons with these dots 8 in the second 2 3 4 5 6 7 and 8 and 1 in the last shell so let's let's let's let label this this is n equals to 3 this is n equals to 2 this is n equals to 1 and this is nucleus now let us do the same things for the chlorine molecule so here again we have nucleus with 17 protons and 18 neutrons as the mass number is 35 and then let's draw the shells so we have first shell, n equals to 1, second, n equals to 2, and third one, that is, n equals to 3.
02:18
In the first one, we have two electrons, 1, 2, in the second one we have 8, 1, 2, 3, 4, 5, 6, 7, 8.
02:31
And in the third one, we have 7.
02:34
So 1, 2, 3, 4, 5, 6, and 7 electrons.
02:40
And the labeling will remain same this is the third this is the second and this is the first shell and this is nucleus so this completes the first part for the second one you have to draw the structure of glucose and fructose so let's start so we have glucose is six carbon so one two three four five and six we have ch2 oh at one and and cho at one end.
03:16
So here we have oh, oh, oh, oh, and h, and h, and h.
03:27
This is carbon number one, and then this is carbon number six.
03:31
So this is the structure of t glucose.
03:36
And now let's draw the structure of fructose.
03:39
Fructose is a keto sugar.
03:41
So we have six carbon again, two, 3, 4, 5 and 6 carbon, but the functional group is ketone and rest we have oh, oh, oh, and hydrogen.
04:01
H, h, h, h, h, h, h, and h.
04:05
So here we will have ch2 -o -h at the end and this is d fructose, which is a ketose sugar...
