C and h bonds
WebAlkanes (C-C and C-H Bonds). Alkanes have C-H and C-C bonds and are the structural foundation for all other organic molecules. While the simplest alkane CH4 has no C-C bonds (it contains only one C), C-C bonds are present in all other alkanes. For example, you can draw a structure for the alkane H3C-CH3 (most often written CH3-CH3) by … WebExplain why HCl has a smaller dipole moment than HF, even though the H—Cl bond is longer than the H—F bond.
