Covalent
C-H bond is stronger
As the bond order of a C-C bond increases, the C-H bond length generally decreases. This is because an increase in bond order indicates a stronger bond, leading to a reduction in bond length. Conversely, a decrease in bond order would result in longer C-H bond lengths.
A single bond.
It is a covalent bond.
The C-C-C bond angle in cumulene is approximately 180 degrees, which is linear. The H-C-H bond angle in cumulene is around 120 degrees, which is trigonal planar.
The bond stretching frequency increases with increasing bond strength. Therefore, the order of increasing bond stretching frequency is: F-H < O-H < N-H < C-H.
The H-C bond and each C-Cl bond are covalent bonds.
there is a C-H bond between two lipids
C₆H₁₂O₆ is a covalent bond.
c=c bond is present in saturated and c-c bond is present in unsaturated
formaldehyde is a trigonal planar with non-ideal H-C-H bond angle, that looks something like this: H \ C=O / H where / and \ are single bonds and = is a double bond
