A polar bond may be present in a nonpolar molecule. Examples: CH4, NH3, C2H2, CO2
A lipid is the most common type of molecule present in the bacteria cell membranes.
No
It is organic if the molecule contains carbon-hydrogen bonds. If none of these bonds are present in the molecule, it is inorganic.
Aldehyde (functional group). The molecule responsible is cinnamaldehyde.
Hydrogen bond
polar covalent
Carbon.
Covalent bonds. (Atom bindings that share electron pairs)
There are two covalent bonds present in a water molecule.
The carbonyl group, -COOH, makes a molecule acidic.
There are five covalent bonds present in an ethyne molecule.
COVALENT bond is present in water
A polar bond may be present in a nonpolar molecule. Examples: CH4, NH3, C2H2, CO2

An actual single molecule is no different in a gaseous, liquid or solid state. However the thermal (kinetic) energy present in it varies between the states.
