Hi everyone in this question the lewis stored structure of each of the following molecules shows only one unshared pair of valence electrons.
00:08
So let us see the case of nitrogen that is n2 molecule and we know this nitrogen belongs to group 15 element in the product table and in the nitrogen it has five valence electron.
00:26
So let us draw the loose structure of.
00:31
For n2 so each nitrogen have five valence electron and we can show like this so so each have five valence electron and we can show like this so therefore the nitrogen have this triple bond can exist and there is two unsheared pair of electron so basically it has two un -shared pair of electron which is also known as lone pair to unsheared pair of electron present in n2 we can also show like this in this way like in terms of octet so each nitrogen has eight electrons now coming to the cl2 and this chlorine basically belongs to group 17 ellie in the product table and has seven valence electron it has seven valence electron so that can be shown like this so one two three four five six seven one two three four five six seven so that mean in chlorine we have single bond and these are the unshed pair of electron now you can see how many unshed pair of electrons so we have one three four one so six unshaired here of electron present in cl2 and this can also be shown in opt -tacept like this now coming to the next molecule that is carbon tetrachloride and in this case we have carbon is the central atom and in carbon it has four valence electron and and the chlorine have seven valence electron so that can be shown like this so carbon have one two three four so these are valence electron of carbon and rest each chlorine have seven valence electron that can be shown like this so it means this carbon then this chlorine this this chlorine this is chlorine this is chlorine now you can see the unshaired pair so one two three four like this so that mean this every chlorine has three unshared pair of electron so in this case each chlorine have three unsheard pair of electron right so carbon has for valence electron and that can make a single bond with each chlorine so that it can form ccl for molecule so we can also show like this so here eight electron this is also have eight electron then it also have eight electron and this also have eight electron and now now like this then coming to the next molecule that is hydrogen peroxide which is h2 o2 so here this we have two oxygen atom and two hydrogen atom so which are arranged in this way and for each hydrogen we have one valence electron and for each oxygen we have six valence electron so that can be show one two, three, four, five, six.
05:03
And similarly, one, two, three, four, five, six.
05:08
And here, each hydrogen has one valence electron.
05:12
So that means hydrogen peroxide can be shown like this hydrogen, oxygen, oxygen, hydrogen.
05:18
And these are unshared pair of electrons.
05:22
So oxygen have two unshed pair of electron.
05:26
So again, this is not.
05:29
So among all of these this is they are not the answers so you can also draw the structure like in this way like this we can show okay so next is ammonia so nitrogen is the central atom and have five valence electron so in this case we have nitrogen having five valence electron that can be show like this one two three four five and now this hydrogen three hydrogen and each hydrogen occupy one valence electron right and that can be shown like this hydrogen nitrogen nitrogen now clearly you can see this so only one unshared pair of electron present in ammonia so only one unshared pair of electron present and this structure can also be shown in this way...
