C-H bond is stronger
h | h-c=o
The H-C bond and each C-Cl bond are covalent bonds.
C=C=C 180 H-C-H 120
No. this is an example of covalent bond, not hydrogen bond
C-H bond is stronger
A slight decrease in C-H bond length as C-C bond order increases. However the change is small.
h | h-c=o
C Polar covalent
Yes. In CH3Cl, there is one C-Cl bond and three C-H bond.
The H-C bond and each C-Cl bond are covalent bonds.

Covalent
1.5 for the C-O bond. and 1 for the C-H bond.
Ionic bond
there is a C-H bond between two lipids
