What type of compound is CH4 ionic or molecular?
WebNonpolar covalent bonds Molecular oxygen Molecular oxygen (O 2) is made from an association between two atoms of oxygen. Since the two atoms share the same electronegativity, the bonds in molecular oxygen are nonpolar covalent. Methane Another example of a nonpolar covalent bond is the C-H bond found in the methane gas (CH 4 ). Web13 apr. 2024 · Polyamidoamine hydrogels prepared by the radical post-polymerization of α,ω-bisacrylamide-terminated M-AGM oligomers, in turn obtained by the polyaddition of 4-aminobutylguanidine with N,N’-methylenebisacrylamide, were reinforced with raw silk fibers, which can establish covalent bonds with the … WebCorrect option is A) In CH4 molecule there exists strong covalent bond between the atoms of each methane molecule whereas, in solid CH4 there exists weak van der waals forces between different methane molecules which is a characterstic of molecula solid. Therefore if we talk about solid CH4 option A is the correct option. Was this answer helpful? all net santo andre
