<p>How do I know if these are molecular or ionic?</p>
<p>B2H6 (the Boron is a metalloid, so I don't know if it should be considered ionic or molecular; I know metal-nonmetal is ionic)</p>
<p>CH3OH (how would I figure it out?)</p>
<p>NOCl (this is a nonmetal and a polyatomic ion; metal-nonmetal is ionic...is that why this is molecular and not ionic?)</p>
<p>Do you mean the bonds in the molcule/compound? Or how to name them?</p>
<p>I think the question refers to the bonding.</p>
<p>They’re all molecular. If they’re ionic, then they’d be able to separate into their ions. For example, NaCl when dissolved becomes Na+ and Cl-. You can’t split up B2H6, CH3OH, or NOCl.</p>
<p>The bonds definitely aren’t ionic (there aren’t any obvious cations and anions paired together). While I’m not sure what you mean by “molecular,” (do you mean “covalent?”) I can assure you that none of those molecules are ionic.</p>
<p>I believe in my class molecular means covalent. My AP Chem textbook actually calls it “molecular” too.</p>
