C and h bonds
WebApr 4, 2024 · Herein, we describe an organocatalytic approach for straightforward acylation of C(sp3)–H bonds employing readily available aldehyde as “acyl source” involving dehydrogenative coupling of aldehydes with ether, amine, or benzylic C(sp3)–H bonds. The developed method affords a broad range of ketones under mild conditions. Web13 hours ago · CH4 is a nonpolar molecule as it has a symmetric tetrahedral geometrical shape with four identical C-H bonds. The electronegativity of carbon and hydrogen is 2.55 and 2.2, respectively, which causes the partial charges to be almost zero. The difference in electrostatic potential is also minimal giving an overall nonpolar molecule.
