Determine if a bond between each pair of atoms would be pure covalent, polar covalent, or ionic. a. Br and Br

Video transcript

All right. Hi everyone. So this question is asking us how does hydrogen exist in the below molecule as H plus H minus or covalent bonding bonded as an H atom? The compound in question is HCL option A says H plus option B says H minus and option C says the H atom is bound covalent. So here, right, recall first and foremost that hydrogen is an atom composed of one proton as well as one electron. Now, generally speaking, hydrogen doesn't tend to transfer its electron during chemical reactions because the ionization energy of hydrogen is actually quite large. So it would be more difficult for that process to happen. And in this case, hydrogen is connected to one atom of chlorine. Now, chlorine is also a non metal and it happens to be quite electron, right, definitely more electron than hydrogen. So here in this case, hydrogen would not transfer the one electron it has instead because Corin residing in group seven A of the periodic table already has seven valence electrons. Hydrogen is instead going to share its electron with chlorine so that chlorine can complete its octet. And likewise because chlorine is also a non metal, it can share its valent electrons with hydrogen through a covalent bond. So therefore, our answer is going to be option c in the multiple choice, right, because hydrogen is going to be bound covalent to chlorine in the compound HCL and there you have it right. So the bottom line here is that both hydrogen and chlorine are non metals capable of sharing their electrons with each other. And with that being said, thank you so very much for watching. And I hope you found this helpful.
